Acceleration Review

Acceleration measures...

• How far an object has travelled

• How long it takes an object to get from one place to another

• How the speed of an object changes over time

Acceleration is a change in _________ or __________.

• speed or direction

• speed or distance

• displacement or speed

If an object is slowing down, what value would the acceleration be?

• positive

• negative

• both positive or negative

• Objects can only speed up

A car starts from rest (0 m/s) and accelerates uniformly to a speed of 5 m/s in 2.5 seconds. The magnitude of the acceleration of the car is

• 2 m/s²

• 2 m/s

• 12.5 m/s²

• 12.5 m/s

A jogger starting from rest accelerates at 0.5 m/s². What is the jogger's change in velocity at the end of 6 seconds.

• 3 m/s

• 3 m/s²

• 12 m/s

• 12 m/s²

Acceleration occurs when there is a change in speed.

• True

• False
