Acceleration Test Prep

Acceleration only takes place when things speed up. 

• True
• False

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval 

Changes in our speed and direction are called _________.

• gravity
• changes
• acceleration
• deceleration

How can you change the acceleration in a car? ( Hint: You can FEEL a change in acceleration)

• The steering wheel 
• The brake pedal
• The gas (the accelerator) 
• All of the above 

Why does a car accelerate as it round a corner at a constant speed?

• Its direction changes
• It doesn't
• It slows down
• Its speeds up  

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

Why does a car accelerate as it round a corner at a constant speed?

• Its direction changes
• It doesn't
• It slows down
• Its speeds up  

Acceleration is defined at a change in velocity. Velocity is ______ 

• Speed in one direction 
• The same thing as speed
• distance/time
• time/distance
