Question

A skateboarder is riding in an empty swimming pool.

How is the potential energy of the skater changed to kinetic energy?
As the skater accelerates down the side of the pool, potential energy is conserved.
As the skater prepares to go down the side of the pool, kinetic energy is changed into potential energy.
As the skater goes down one side of the pool and up the other, potential energy changes to kinetic energy.
As the skater rests at the bottom of the pool, potential energy is gained.

Answer 1

Answer:As the skater goes down one side of the pool and up the other, potential energy changes to kinetic energy. At the top of the pool, the skateboarder has the most potential energy and the least kinetic energy, and at the bottom of the pool, the skateboarder has the most kinetic energy and the least potential energy. As the skateboarder rides down the side of the pool, the potential energy is converted into kinetic energy, causing the skateboarder to accelerate. At the bottom of the pool, all the potential energy has been converted to kinetic energy. As the skateboarder goes up the other side of the pool, the kinetic energy is gradually converted back into potential energy, causing the skateboarder to slow down and eventually come to a stop at the top of the other side.
