A ball is thrown straight up into the air with an initial upward velocity. Suppose we call the up direction positive.

What happens to its velocity from the time it is released to the time it reaches its highest point?

Its velocity increases

Its velocity decreases until it becomes negative

Its velocity decreases until it reaches zero

Its velocity stays the same

What happens to its velocity from the time it reaches its highest point to the time it is caught?

Its velocity decreases from zero and becomes more negative

Its velocity stays the same

Its velocity increases from zero

Its velocity decreases until it reaches zero

What happens to the its acceleration from release to catch?

It remains constant throughout the motion

It increases

It decreases

Is the ball's acceleration ever zero while in flight?

No

Yes
