At the beginning of the period, we turned in our Energy test reviews. Then we got our calculators and Mr. Ebersole passed out the Energy test, which we took for the rest of the period.

Describe the types of energy you have as you go around a roller coaster loop.

As you go up a loop, you increase your gravitational potential energy and inversely decrease your kinetic energy. As you go down a loop, you decrease your gravitational potential energy and increase your kinetic energy. Throughout the whole process, the total mechanical energy stays the same amount. However, because of friction, some of the energy when you go around the loop is lost as heat.
