Newton’s 1st law

Newton’s 2nd law

Newton’s 3rd law

Law of Gravity

Words of Motion F J

An object will be harder to move if

it has more of this.

2

What is mass.(or matter)

3

A moving object tends to stay in

motion unless this acts on.

4

What is an unbalanced

force?5

This is the kind of forces acting on a book not moving

on a desk.

6

What are balanced forces?

7

This force slows down many

objects on earth.

8

What is friction?

9

Newton’s 1st law can be summed up in this one

word. 10

What is inertia?

11

This will happen to an object that

has a force applied to it.

12

What is accelerate?

13

If you increase the force on a moving

object this will happen to the acceleration.

14

What isit will increase?

15

If you increase the mass of an object, this will happen to the acceleration.

16

What isit will decrease?

17

These 2 things determine the acceleration of

any object. 18

What are mass and force?

19

This equation explains the

relationship between force, mass, and

acceleration.20

What is F = m X a ?

(Or any member of the fact family.)

21

22

If you throw a heavy ball while you are wearing skates, this will

probably happen.

23

What is you’ll be pushed back

by the ball?

24

Every action has an equal and opposite

one of these.

25

What is reaction?

26

When a balloon flies across a

room because of air pressure, the

push of air is this.

What is the action?

27

28

When the thrust of a rocket pushes it into space, the moving

rocket is this.

29

What is the reaction?

30

This is the reaction when rowers use their oars to push

water.

What is the boat moves forward?

31

A feather will fall more slowly

than a rock because of this.

32

What is air resistance?

33

34

This scientist found that without air

resistance, heavy and light objects fall at

the same rate.

Who is Galileo?

35

As an object falls, it’s velocity does

this.

36

What is it increases?

(or accelerates.)

37

Objects close to earth accelerate at this rate as they

fall.38

What is 9.8 m/s2?(meters per second, each second)

39

The moon stays in orbit because of these two forces.

40

What are gravity and

inertia?41

Objects with mass pull each other because of this.

42

What is gravity?

43

How fast an object changes

position.

44

What is speed?

45

The speed and direction of a

moving object.

46

What is velocity?

47

A push or a pull that can be either

balanced or unbalanced.

48

What is a force?

49

It measures how much gravity

pulls an object.

50

What is weight?

51

Final Jeopardy

52

FINAL JEOPARDY

This ancient scientist thought heavy objects fall faster than light

ones.53

Who is Aristotle?
