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 kinetic and potential energy affected? when is each type of energy the greatest and the least? what is true about the total mechanical energy of the ball?

When you are holding the ball it has potential energy and when you through it it will then have kinetic energy as it go's up then it will pause for a brief sec. and then that 's when it has the greatest potential energy and then when it falls back down is when it has the greatest kinetic energy. The mechanical energy would be when you through the ball.

Hope this helps:)

Liquid. good luck : )
