Motion Are distance and time important in describing running

events at the track-and-field meets in the Olympics Would thewinners of the 5-km race and the 10-km race complete the runin the same length of time

Distance and time are important In order to win a race youmust cover the distance in the shortest amount of time Thetime required to run the 10-km race should be longer than thetime needed to complete the 5-km race because the first distanceis longer How would you describe the motion of the runners inthe two races

Motion and Position You donrsquot always need to see some-thing move to know that motion has taken place For examplesuppose you look out a window and see a mail truck stoppednext to a mailbox One minute later you look out again and seethe same truck stopped farther down the street Although youdidnrsquot see the truck move you know it moved because its posi-tion relative to the mailbox changed

A reference point is needed to determine the position of anobject In Figure 1 the reference point might be a tree or a mail-box Motion occurs when an object changes its position relativeto a reference point The motion of an object depends on thereference point that is chosen For example the motion of themail truck in Figure 1 would be different if the reference pointwere a car moving along the street instead of a mailbox

SECTION 1 Describing Motion 39

Frame of Reference After a reference point is chosen aframe of reference can be created A frame of reference is a coor-dinate system in which the position of the objects is measuredThe x-axis and y-axis of the reference frame are drawn so thatthey intersect the reference point

Distance In track-and-field events have you ever run a 50-mdash A distance of 50 m was marked on the track or athletic fieldto show you how far to run An important part of describing themotion of an object is to describe how far it has moved which isdistance The SI unit of length or distance is the meter (m)Longer distances are measured in kilometers (km) One kilome-ter is equal to 1000 m Shorter distances are measured in cen-timeters (cm) One meter is equal to 100 centimeters

Displacement Suppose a runner jogs to the 50-m mark andthen turns around and runs back to the 20-m mark as shown inFigure 2 The runner travels 50 m in the original direction(north) plus 30 m in the opposite direction (south) so the totaldistance she ran is 80 m How far is she from the starting lineThe answer is 20 m Sometimes you may want to know not onlyyour distance but also your direction from a reference pointsuch as from the starting point Displacement is the distanceand direction of an objectrsquos change in position from the startingpoint The runnerrsquos displacement in Figure 2 is 20 m north

The length of the runnerrsquos displacement andthe distance traveled would be the same if therunnerrsquos motion was in a single direction If therunner ran from the starting point to the finishline in a straight line then the distance traveledwould be 50 m and the displacement would be50 m north

How do distance anddisplacement differ

Speed Think back to the example of the mail truckrsquos

motion in Figure 1 You could describe themovement by the distance traveled and by thedisplacement from the starting point You alsomight want to describe how fast it is moving Todo this you need to know how far it travels in agiven amount of time Speed is the distance anobject travels per unit of time

Calculating Speed Any change over time is called a rate Ifyou think of distance as the change in position then speed is therate at which distance is traveled or the rate of change in position

The SI unit for distance is the meter and the SI unit of time isthe second (s) so in SI units of speed are measured in meters persecond (ms) Sometimes it is more convenient to express speedin other units such as kilometers per hour (kmh) Table 1 showssome convenient units for certain types of motion

Solve a One-Step Equation

1 A passenger elevator operates at an average speed of 8 ms If the 60th floor is 219 m above

the first floor how long does it take the elevator to go from the first floor to the 60th floor

2 A motorcyclist travels an average speed of 20 kmh If the cyclist is going to a friendrsquos house

5 km away how long does it take the cyclist to make the trip

Motion with Constant Speed Suppose you are in a car trav-eling on a nearly empty freeway You look at the speedometer andsee that the carrsquos speed hardly changes If the car neither slows downnor speeds up the car is traveling at a constant speed If you aretraveling at a constant speed you can measure your speed over anydistance interval

Changing Speed Usually speed is not constant Think aboutriding a bicycle for a distance of 5 km as in Figure 3 As you startout your speed increases from 0 kmh to 20 kmh You slow downto 10 kmh as you pedal up a steep hill and speed up to 30 kmhgoing down the other side of the hill You stop for a red lightspeed up again and move at a constant speed for a while Finallyyou slow down and then stop Checking your watch you find thatthe trip took 15 min How would you express your speed on sucha trip Would you use your fastest speed your slowest speed orsome speed between the two

Figure 3 The graph shows howthe speed of a cyclist changesduring a tripExplain how you describe thespeed of an object when the speedis changing

42 CHAPTER 2 Motion

Average Speed Average speed describes speed of motionwhen speed is changing Average speed is the total distance trav-eled divided by the total time of travel It can be calculated usingthe relationships among speed distance and time For the bicy-cle trip just described the total distance traveled was 5 km andthe total time was 14 h or 025 h The average speed was

Instantaneous Speed Suppose you watch a carrsquos speed-ometer like the one in Figure 4 go from 0 kmh to 60 kmh Aspeedometer shows how fast a car is going at one point in timeor at one instant The speed shown on a speedometer is theinstantaneous speed Instantaneous speed is the speed at agiven point in time

Changing Instantaneous Speed When something isspeeding up or slowing down its instantaneous speed is chang-ing The speed is different at every point in time If an object ismoving with constant speed the instantaneous speed doesnrsquotchange The speed is the same at every point in time

What are two examples of motion in which theinstantaneous speed changes

Graphing MotionThe motion of an object over a period of time can be shown

on a distance-time graph Time is plotted along the horizontalaxis of the graph and the distance traveled is plotted along the ver-tical axis of the graph If the object moves with constant speed theincrease in distance over equal time intervals is the same As aresult the line representing the objectrsquos motion is a straight line

For example the graph shown in Figure 5 represents themotion of three swimmers during a 30-min workout Thestraight red line represents the motion of Mary who swam witha constant speed of 80 mmin over the 30-min workout Thestraight blue line represents the motion of Kathy who swamwith a constant speed of 60 mmin during the workout

The graph shows that the line representing the motion of thefaster swimmer is steeper The steepness of a line on a graph is theslope of the line The slope of a line on a distance-time graph equalsthe speedA horizontal line on a distance-time graph has zero slopeand represents an object at rest Because Mary has a larger speedthan Kathy the line representing her motion has a larger slope

Changing Speed The green line represents the motion ofJulie who did not swim at a constant speed She covered 400 mat a constant speed during the first 10 min rested for the next10 min and then covered 800 m during the final 10 minDuring the first 10 min her speed was less than Maryrsquos orKathyrsquos so her line has a smaller slope During the middleperiod her speed is zero so her line over this interval is hori-zontal and has zero slope During the last time intervalshe swam as fast as Mary so that part of her line has thesame slope

Plotting a Distance-Time Graph On a distance-timegraph the distance is plotted on the vertical axis and the timeon the horizontal axis Each axis must have a scale that coversthe range of numbers to be plotted In Figure 5 the distancescale must range from 0 to 2400 m and the time scale mustrange from 0 to 30 min Then each axis can be divided intoequal time intervals to represent the data Once the scalesfor each axis are in place the data points can be plottedAfter plotting the data points draw a line connecting thepoints

Figure 6 The speed of a storm isnot enough information to plot thepath The direction the storm ismoving must be known too

Velocity You turn on the radio and hear the tail end of

a news story about a hurricane like the one inFigure 6 that is approaching land The stormtraveling at a speed of 20 kmh is located 100 kmeast of your location Should you be worried

Unfortunately you donrsquot have enough infor-mation to answer that question Knowing onlythe speed of the storm isnrsquot much help Speeddescribes only how fast something is moving Todecide whether you need to move to a safer areayou also need to know the direction that thestorm is moving In other words you need to

know the velocity of the storm Velocity includes the speed of anobject and the direction of its motion

Escalators like the one shown in Figure 7 are found in shop-ping malls and airports The two sets of passengers pictured aremoving at constant speed but in opposite directions Thespeeds of the passengers are the same but their velocities are dif-ferent because the passengers are moving in different directions

Because velocity depends on direction as well as speed thevelocity of an object can change even if the speed of the objectremains constant For example look at Figure 7 The race carhas a constant speed and is going around an oval track Eventhough the speed remains constant the velocity changesbecause the direction of the carrsquos motion is changing constantly

How are velocity and speed different Figure 7 For an object to haveconstant velocity speed and direc-tion must not be changing

The speed of this car might be constant but itsvelocity is not constant because the direction ofmotion is always changing

The people on these two escalators have the samespeed However their velocities are differentbecause they are traveling in opposite directions

Motion of Earthrsquos Crust Can you think of something that is mov-ing so slowly you cannot detect its motion

yet you can see evidence of its motion over long periods of timeAs you look around the surface of Earth from year to year thebasic structure of the planet seems the same Mountains plainslakes and oceans seem to remain unchanged over hundreds ofyears Yet if you examined geological evidence of what Earthrsquossurface looked like over the past 250 million years you wouldsee that large changes have occurred Figure 8 shows howaccording to the theory of plate tectonics the positions of land-masses have changed during this time Changes in the landscapeoccur constantly as continents drift slowly over Earthrsquos surfaceHowever these changes are so gradual that you do not noticethem

250 million years ago

Present day


About 250 million years ago the continentsformed a supercontinent called Pangaea

Pangaea began to separate into smallerpieces and by 66 million years ago thecontinents looked like the figure aboveThe continents are still moving today

Figure 8 Geological evidencesuggests that Earthrsquos continentshave moved slowly over time

Moving Continents How can continents move around on thesurface of Earth Earth is made of layers as shown in Figure 9The outer layer is the crust and the layer just below the crust iscalled the upper mantle Together the crust and the top part of theupper mantle are called the lithosphere The lithosphere is brokeninto huge sections called plates that slide slowly on the puttylikelayers just below If you compare Earth to an egg these plates areabout as thick as the eggshell These moving plates cause geolog-ical changes such as the formation of mountain ranges earth-quakes and volcanic eruptions

The movement of the plates also is changing the size of theoceans and the shapes of the continents The Pacific Ocean isgetting smaller while the Atlantic Ocean is getting larger Themovement of the plates also changes the shape of the continentsas they collide and spread apart

Plates move so slowly that their speeds are given in units ofcentimeters per year In California two plates slide past eachother along the San Andreas Fault with an average relative speedof about 1 cm per year The Australian Platersquos movement is oneof the fastest pushing Australia north at an average speed ofabout 17 cm per year

SECTION 2 Acceleration 47

Acceleration Speed and Velocity Yoursquore sitting in a car at a stoplight when the light turns

green The driver steps on the gas pedal and the car starts mov-ing faster and faster Just as speed is the rate of change of posi-tion acceleration is the rate of change of velocity When thevelocity of an object changes the object is accelerating

Remember that velocity includes the speed and direction ofan object Therefore a change in velocity can be either a changein how fast something is moving or a change in the direction itis moving Acceleration occurs when an object changes its speedits direction or both

Speeding Up and Slowing Down When you think ofacceleration you probably think of something speeding upHowever an object that is slowing down also is accelerating

Imagine a car traveling through a city If the speed isincreasing the car has positive acceleration When the carslows down its speed is decreasing and the car has negativeacceleration In both cases the car is accelerating because itsspeed is changing

Acceleration also has direction just as velocity does Ifthe acceleration is in the same direction as the velocity as in Figure 10 the speed increases and the acceleration is positive Ifthe speed decreases the acceleration is in the opposite directionfrom the velocity and the acceleration is negative for the carshown in Figure 10

48 CHAPTER 2 Motion

Changing Direction A change in velocity can be eithera change in how fast something is moving or a change inthe direction of movement Any time a moving objectchanges direction its velocity changes and it is accelerat-ing Think about a horse on a carousel Although thehorsersquos speed remains constant the horse is acceleratingbecause it is changing direction constantly as it travels ina circular path as shown in Figure 11 In the same wayEarth is accelerating constantly as it orbits the Sun in anearly circular path

Graphs of speed versus time can provide informationabout accelerated motion The shape of the plotted curve

shows when an object is speeding up or slowing down Figure 12shows how motion graphs are constructed

Calculating Acceleration Acceleration is the rate of change in velocity To calculate the

acceleration of an object the change in velocity is divided by thelength of the time interval over which the change occurred

To calculate the change in velocity subtract the initial veloc-itymdashthe velocity at the beginning of the time intervalmdashfromthe final velocitymdashthe velocity at the end of the time intervalLet vi stand for the initial velocity and vf stand for the finalvelocity Then the change in velocity is

Using this expression for the change in velocity the accelerationcan be calculated from the following equation

Recall that velocity includes both speed and directionHowever if the direction of motion doesnrsquot change and theobject moves in a straight line the change in velocity is the sameas the change in speed The change in velocity then is the finalspeed minus the initial speed

The unit for acceleration is a unit for velocity divided by aunit for time In SI units velocity has units of ms and time hasunits of s so acceleration has units of ms2

Calculating Positive Acceleration How is the accelera-tion for an object that is speeding up different from that of anobject that is slowing down Suppose the jet airliner in Figure 13starts at rest at the end of a runway and reaches a speed of80 ms in 20 s The airliner is traveling in a straight line downthe runway so its speed and velocity are the same Because itstarted from rest its initial speed was zero Its acceleration canbe calculated as follows

The airliner is speeding up so the final speed is greater than theinitial speed and the acceleration is positive

Calculating Negative Acceleration Now imagine thatthe skateboarder in Figure 13 is moving in a straight line at aconstant speed of 3 ms and comes to a stop in 2 s The finalspeed is zero and the initial speed was 3 ms The skateboarderrsquosacceleration is calculated as follows

The skateboarder is slowing down so the final speed is lessthan the initial speed and the acceleration is negative The accel-eration always will be positive if an object is speeding up andnegative if the object is slowing down

SummaryAcceleration Speed and Velocity

bull Acceleration is the rate of change of velocity

bull A change in velocity occurs when the speed ofan object changes or its direction of motionchanges or both occur

bull The speed of an object increases if the acceler-ation is in the same direction as the velocity

bull The speed of an object decreases if the accel-eration and the velocity of the object are inopposite directions

Calculating Acceleration

bull Acceleration can be calculated by dividing thechange in velocity by the time according tothe following equation

bull The SI unit for acceleration is ms2

Amusement Park AccelerationRiding roller coasters in amusement parks can give you the

feeling of danger but these rides are designed to be safeEngineers use the laws of physics to design amusement park ridesthat are thrilling but harmless Roller coasters are constructed ofsteel or wood Because wood is not as rigid as steel wooden rollercoasters do not have hills that are as high and steep as some steelroller coasters have As a result the highest speeds and accelera-tions usually are produced on steel roller coasters

Steel roller coasters can offer multiple steep drops and inver-sion loops which give the rider large accelerations As the ridermoves down a steep hill or an inversion loop he or she willaccelerate toward the ground due to gravity When riders goaround a sharp turn they also are accelerated This accelerationmakes them feel as if a force is pushing them toward the sideof the car Figure 14 shows the fastest roller coaster in theUnited States

What happens when riders on a roller coaster goaround a sharp turn

52 CHAPTER 2 Motion

What is forcePassing a basketball to a team member or kicking a soccer ball

into the goal are examples of applying force to an object A forceis a push or pull In both examples the applied force changes themovement of the ball Sometimes it is obvious that a force hasbeen applied But other forces arenrsquot as noticeable For instanceare you conscious of the force the floor exerts on your feet Canyou feel the force of the atmosphere pushing against your body orgravity pulling on your body Think about all the forces you exertin a day Every push pull stretch or bend results in a force beingapplied to an object

Changing Motion What happens to themotion of an object when you exert a forceon it A force can cause the motion ofan object to change Think of hitting a ballwith a racket as in Figure 15 The racketstrikes the ball with a force that causes theball to stop and then move in the oppositedirection If you have played billiards youknow that you can force a ball at rest to rollinto a pocket by striking it with another ballThe force of the moving ball causes the ballat rest to move in the direction of the forceIn these cases the velocities of the ball andthe billiard ball were changed by a force

Balanced Forces Force does not always change velocity InFigure 16A two students are pushing on opposite sides of a boxBoth students are pushing with an equal force but in oppositedirections When two or more forces act on an object at thesame time the forces combine to form the net force The netforce on the box in Figure 16A is zero because the two forcescancel each other Forces on an object that are equal in size andopposite in direction are called balanced forces

Unbalanced Forces Another example of how forces com-bine is shown in Figure 16B When two students are pushingwith unequal forces in opposite directions a net force occurs inthe direction of the larger force In other words the student whopushes with a greater force will cause the box to move in thedirection of the force The net force that moves the box will bethe difference between the two forces because they are in oppo-site directions They are considered to be unbalanced forces

In Figure 16C the students are pushing on the box in the samedirection These forces are combined or added together becausethey are exerted on the box in the same direction The net forcethat acts on this box is found by adding the two forces together

Give another example of an unbalanced force

These students are pushing onthe box in the same direction Thecombined forces will cause the boxto move

54 CHAPTER 2 Motion

Inertia and Mass The dirt bike in Figure 17 is sliding on the track This sliding

bike demonstrates the property of inertia Inertia (ih NUR shuh)is the tendency of an object to resist any change in its motion Ifan object is moving it will have uniform motion It will keepmoving at the same speed and in the same direction unless anunbalanced force acts on it The velocity of the object remainsconstant unless a force changes it If an object is at rest it tendsto remain at rest Its velocity is zero unless a force makes it move

Does a bowling ball have the same inertia as a table-tennisball Why is there a difference You couldnrsquot change the motionof a bowling ball much by swatting it with a table-tennis paddleHowever you easily could change the motion of the table-tennisball A greater force would be needed to change the motion ofthe bowling ball because it has greater inertia Why is this Recallthat mass is the amount of matter in an object and a bowlingball has more mass than a table-tennis ball does The inertia ofan object is related to its mass The greater the mass of an objectis the greater its inertia

Newtonrsquos Laws of Motion Forces change the motion of anobject in specific ways The British scientist Sir Isaac Newton(1642ndash1727) was able to state rules that describe the effects offorces on the motion of objects These rules are known asNewtonrsquos laws of motion They apply to the motion of all objectsyou encounter every day such as cars and bicycles as well as themotion of planets around the Sun

Figure 17 This racer is skiddingbecause of inertia The bike tendsto move in a straight line withconstant speed despite the effortsof the rider to steer the bikearound the curve

Observing Inertia Procedure1 Create an inclined plane

between 25deg and 50deg usinga board and textbooksPlace a stop block (brick orother heavy object) at theend of the plane

2 Place a small object in acart and allow both to rolldown the plane Recordthe results in your ScienceJournal

3 Secure the object in thecart with rubber bands(safety belts) Allow bothto roll down the planeagain Record the results

Analysis1 Identify the forces acting

on the object in both runs2 Explain why it is important

to wear safetybelts in a car

Figure 18 The inertia of thebilliard balls causes them toremain at rest until a force isexerted on them by the cue ball

Newtonrsquos First Law of Motion Newtonrsquos first law ofmotion states that an object moving at a constant velocity keepsmoving at that velocity unless an unbalanced net force acts onit If an object is at rest it stays at rest unless an unbalanced netforce acts on it Does this sound familiar It is the same as theearlier discussion of inertia This law is sometimes called the lawof inertia You probably have seen and felt this law at work with-out even knowing it Figure 18 shows a billiard ball striking theother balls in the opening shot What are the forces involvedwhen the cue ball strikes the other balls Are the forces balancedor unbalanced How does this demonstrate the law of inertia

What is Newtonrsquos first law of motion

What happens in a crash The law of inertia can explain what happens in a

car crash When a car traveling about 50 kmh collideshead-on with something solid the car crumples slowsdown and stops within approximately 01 s Any pas-senger not wearing a safety belt continues to moveforward at the same speed the car was travelingWithin about 002 s (150 of a second) after the carstops unbelted passengers slam into the dashboardsteering wheel windshield or the backs of the frontseats as in Figure 19 They are traveling at the carrsquosoriginal speed of 50 kmhmdashabout the same speedthey would reach falling from a three-story building

56 CHAPTER 2 Motion

Self Check1 Infer whether the inertia of an object changes as the

objectrsquos velocity changes

2 Explain whether or not there must be an unbalancednet force acting on any moving object

3 Explain Can there be forces acting on an object if theobject is at rest

4 Infer the net force on a refrigerator if you push on therefrigerator and it doesnrsquot move

5 Think Critically Describe three situations in which aforce changes the velocity of an object

SummaryWhat is Force

bull A force is a push or a pull on an object

bull The net force on an object is the combinationof all the forces acting on the object

bull When the forces on an object are balancedthe net force on the object is zero

bull Unbalanced forces cause the motion of objectsto change

Inertia and Newtonrsquos First Law of Motion

bull The inertia of an object is the tendency of anobject to resist a change in motion

bull The larger the mass of an object the greaterits inertia

bull Newtonrsquos first law of motion states that themotion of an object at rest or moving withconstant velocity will not change unless anunbalanced net force acts on the object

bull In a car crash inertia causes an unrestrainedpassenger to continue moving at the speed ofthe car before the crash

6 Calculate Net Force Two students push on a box in thesame direction and one pushes in the opposite directionWhat is the net force on the box if each pushes with aforce of 50 N

7 Calculate Acceleration The downward force of grav-ity and the upward force of air resistance on a ball are both 5 N What is the ballrsquos acceleration

Safety Belts The crash dummy wearing asafety belt in Figure 20 is attached to the carand slows down as the car slows down Theforce needed to slow a person from 50 kmh tozero in 01 s is equal to 14 times the force thatgravity exerts on the person The belt loosensa little as it restrains the person increasing thetime it takes to slow the person down Thisreduces the force exerted on the person Thesafety belt also prevents the person from beingthrown out of the car Car-safety experts saythat about half the people who die in carcrashes would survive if they wore safety beltsThousands of others would suffer fewer seri-ous injuries

Air bags also reduce injuries in car crashes by providing acushion that reduces the force on the carrsquos occupants Whenimpact occurs a chemical reaction occurs in the air bag thatproduces nitrogen gas The air bag expands rapidly and thendeflates just as quickly as the nitrogen gas escapes out of tinyholes in the bag The entire process is completed in about 004 s


Figure 20 These crash dummieswere restrained safely with safetybelts in this low-speed crashUsually humans would have fewerinjuries if they were restrainedsafely during an accident

Describing Motion

1 Motion is achange of positionof a body Dis-tance is the mea-sure of how far anobject movedDisplacement isthe distance anddirection of an objectrsquos change in positionfrom the starting point

2 A reference point must be specified inorder to determine an objectrsquos position

3 The speed of an object can be calculatedfrom this equation

s dt

4 The slope of a line on a distance-timegraph is equal to the speed

5 Velocity describes the speed and directionof a moving object

Acceleration

1 Acceleration occurs when an object changesspeed or changes direction

2 An object speeds up if its acceleration is inthe direction of its motion

3 An object slows down if its acceleration isopposite to the direction of its motion

4 Acceleration is the rate of change of veloc-ity and is calculated from this equation

tvi

Motion and Forces

1 A force is a push or a pull

2 The net force acting on an object is thecombination of all the forces acting on theobject

3 The forces on an object are balanced if thenet force is zero

4 Inertia is the resistance of an object to achange in motion

5 According to Newtonrsquos first law of motionthe motion of an object does not changeunless an unbalanced net force acts on theobject

Motion Many things are inmotion in your everyday lifeMake the following Foldable to

help you better understand motion as you readthe chapter

Fold a sheet of paper in half length-wise Make the back edge about125 cm longer than the front edge

Fold in half then fold inhalf again to make threefolds

Unfold and cut only the top layer alongthe three folds to make four tabs

Label the tabs

Identify Questions Before you read the chap-ter select a motion you can observe and write itunder the left tab As you read the chapter writeanswers to the other questions under the appro-priate tabs

STEP 4

STEP 3

STEP 2

STEP 1

Compare SpeedsA cheetah can run at a speed of almost120 kmh and is the fastest runner in theworld A horse can reach a speed of 64 kmhan elephantrsquos top speed is about 40 kmhand the fastest snake slithers at a speedof about 3 kmh The speed of an object iscalculated by dividing the distance the objecttravels by the time it takes it to move thatdistance How does your speed compare tothe speeds of these animals

1 Use a meterstick to mark off 10 m

2 Have your partner use a stopwatch todetermine how fast you run 10 m

3 Divide 10 m by your time in seconds tocalculate your speed in ms

4 Multiply your answer by 36 to determineyour speed in kmh

5 Think Critically Write a paragraph inyour Science Journal comparing yourspeed with the maximum speed of acheetah horse elephant and snakeCould you win a race with any of them
