The change in velocity in a given time period is?

• initial velocity

• final velocity

• acceleration

• displacement

When speed and direction remain the same throughout motion, this is called?

• Accelerated motion

• Constant motion

• Changing motion

• Changing velocity

Which would hit the ground first if dropped from the same height in a vacuum—a feather or a metal bolt?

• the feather

• the metal bolt

• They would hit the ground at the same time.

• They would be suspended (floating) in a vacuum.

A ball is thrown upwards and caught when it comes back down at the same height. 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.

• need more information to determine.
