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?

As the ball is released, it has maximum kinetic energy and no potential energy. This kinetic energy is converted to potential energy as the ball travels upwards, and at the top of its path, there is no kinetic energy, only potential energy. As the ball starts falling again, this potential energy is converted to kinetic energy.

The mechanical energy is the sum of kinetic and potential energies and it remains constant.
