Question

how do the potential energy and the kinetic energy change when the skateboard is at the top or the bottom of the hill? why do you think this change occurs?

Answer 1

As the skateboarder goes down the ramp, potential energy is converted to kinetic energy

Step-by-step explanation:

Because of friction, some of the energy in the system is converted to heat energy. Once the kinetic energy is converted to heat, the energy cannot be converted back to the potential or kinetic energy in the system.
