Chapter 2.2 Objectives and Vocabulary acceleration

deceleration Newton's

second law

Define and calculate acceleration.

Explain the relationship between force, mass, and acceleration.

Determine mass, acceleration and force given two of the quantities.

Chapter 2.3 Objectives and Vocabulary free fall

acceleration due to gravity

velocity weight air resistance terminal speed

Describe the motion of an object in free fall.

Calculate the speed and distance for an object in free fall.

Distinguish between mass and weight.

Explain how air resistance affects the motion of objects.

An object is in free fall if it is

accelerating due to the force of gravity

and no other forces are acting

on it.

Falling objects increase their speed by 9.8 m/s every second, or 9.8 m/s2

The letter “g” is used for acceleration due to gravity.

Chapter 2.4 Objectives and Vocabulary slope Describe motion with position

versus time and speed versus time graphs.

Use a position versus time graph to calculate speed from the slope.

Use a speed versus time graph to calculate acceleration and distance traveled.
