Describe the motion of a ball being thrown straight up in the air in terms of kinetic and potential energy. as the ball rises up and falls back down, how is its kinectic and potential energy affected?

In your hand, the ball has higher potential energy than kinetic because it is still off of the ground but it isn't moving so there is no kinetic. As the ball rises, its potential and kinetic energy increases. At its peak, it has very high potential energy and very low kinetic energy. As it falls, the potential energy decreases but kinetic does not.
