Given the sketch of a conservative roller coaster ride, discuss the aspects of Energy conservation. At each position, A, B, C, and D discuss the values of total, potential, and kinetic energy. The position of A = R, position of B = R/2, position of C is 3xR/4 and the position of D = 0. Label what you know and conclude about each position (A, B, C, D)
