Question

What happened to the potential energy and the kinetic energy as the skater went up and down the ramp? Why does this happen?

Answer 1

As the skater went down the ramp, his kinetic energy increased but his potential energy decreased. As the skater went up the ramp, he gained potential energy and lost kinetic energy. This happens because gravity causes the skater to gain speed as he descends. As the skater moves up the ramp, he loses speed, so kinetic energy decreases.

Answer 2

Hey there!

Here is your answer:

The proper answer to this question is "both energy's increase, and decrease while moving up and down the ramp".

Reason:

Kinetic energy is the speed a object is going, and potential energy is the energy a object has when its not moving. While the skater moves up the ramp the potential energy increases, and the kinetic energy decreases because it slows down while moving up the ramp. Then as the skater moves down the ramp then kinetic energy will increase, and kinetic energy will increase which is what these two energy's have in common!
