Why does the potential energy and the kinetic energy change when the skateboarder is at the top or the bottom of the hill why do you think this change occurs

Potential energy is gaining all the way to the top of the hill due to the increase of height (gravitational pull) on the skateboarder. At the top of the hill potential energy will reach its highest point. Then going down kinetic energy increases as potential energy decreases.

Explanation:

Answer : The potential energy and kinetic energy are always in flux. At the top of the hill, potential energy is at its highest and kinetic energy is at its lowest because the skateboarder stops for just a moment before being pulled down the hill by the force of gravity. At the bottom of the hill, kinetic energy is the highest because the skateboarder reaches maximum speed
