Acceleration Test Review

Acceleration only takes place when things speed up. 

• True
• False

In which case does the car have no acceleration ?

• A car speeding up shortly after a stoplight turns green.

• A car slowing down approaching a red light

• A car traveling at a constant speed of 80 km/h

• A car stopped at a red light

An object slowing down has

• negative acceleration

• no acceleration

• positive acceleration

An object speeding up has

• negative acceleration

• no acceleration

• positive acceleration

Which car has the fastest acceleration?

• Car goes from 0-60 Mph in 3 seconds
• Car goes from 0-60 Mph in 4 seconds
• Car goes from 0-60 Mph in 5 seconds
• Car goes from 0-60 Mph in 6 seconds

Acceleration is

• rate of change of velocity over time.

• how far an object has moved.

• the distance an object travels per unit of time.

• the speed of an object and the direction of its motion.

Match the following graphs to the right description.

• No acceleration (constant speed)

• 
• Speeding up

• 
• Slowing down
