1. Set the skater into simple back and forth motion as before on the first track that is a simple U shape, and look at the Energy Bar Chart. Can you see how the rightmost bar labeled Total is remaining constant? The fact that is stays constant is a demonstration of the Law of...

1. Now look at the Kinetic and Potential bars. As Kinetic Energy increases, Potential Energy....

1. Try turning on friction and letting your skater start from the top of the track. Notice how the available energy is transforming into Thermal Energy.
   1. If you wait long enough, will the Thermal Energy transform back into Kinetic and Potential Energy?

No, it will not turn back to KE and PE

1. Will the skater eventually stop moving with the friction turned on? Describe what you observe about the amounts of the different forms of energy as time goes on.

Yes the skater will eventually come to a stop with the friction turned on. I observed that there are many different forms of energy but the most important are KE and PE because in a world where "doing something" is essential, KE and PE become essential.
