Kinematics Review (required)

What is the displacement from 0-5 seconds?

• 25 m away
• 5 m away 
• 6 m away
• 15 m away

What is the average velocity from 0-5 seconds?

Displacement definition

• Total distance divided by time
• Displacement divided by time
• Change in position with direction
• Change in velocity divided by time

The distance-time graphs shown represent the motion of a car. Which of the following graphs represents the car at constant, positive velocity?

A ball is thrown upwards and caught when it comes back down. In the absence of air resistance, the speed of the ball when caught would be 

• less than the speed it had when thrown upwards.
• more than the speed it had when thrown upwards.
• the same as the speed it had when thrown upwards.
