However, energy can change from one form to another. In the case of a marble on a paper roller coaster, a marble starts at the top of the roller coaster with a relatively large amount of potential energy and no ic energy. As the marble starts rolling down the roller coaster, the amount of potential energy stored in the marble decreases while its ic energy increases. Potential energy is also converted into heat energy due to friction. In this experiment, you will be calculating the change in potential energy of a marble traveling between two points on a paper roller coaster pare that to the ic energy that was gained by the marble during that same time. EQUIPMENT pleted Paper Roller Coaster ruler pencil calculator ???? stopwatch (optional) video camera (optional) photogate timer (optional) ??? PROCEDURE I. Selecting the starting and ending points. Choose a portion of the roller coaster in which the marble accelerates and then keeps a fairly constan
