Roller coaster exercise Consider the following roller coaster layout taken from the eScience manual: C Based on your understanding of energy concepts, please answer the following questions. Make sure to include detailed physical arguments. • What happens to the roller coaster's kinetic energy between points 13 and C? What happens to its potential energy between these points? Why is it important for A to be higher than C? • If the roller coaster starts at point A, can it ever go higher than this point? What causes the roller coaster train to lose energy over its trip? . List the points in order of greatest potential energy to least.
