Question

energy transfer
on a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. which statement is not true regarding the energy of the roller coaster shown
a the car at point c has less kinetic energy than the car at point b
b the car at point a has more kinetic energy than the car at point c
c a car at point d has more potential energy than the car at point b
d a car at point a has more potential energy than the car at point c

Explanation:

Potential energy is related to height and kinetic energy is related to speed. At higher - points, potential energy is higher and kinetic energy is lower. At lower - points, kinetic energy is higher and potential energy is lower. Point A is the highest point, so it has the most potential energy. Point B is a lower point, so it has more kinetic energy than points A and C. Point C is higher than point B, so it has less kinetic energy than point B. Point D is higher than point B, so it has more potential energy than point B. Point A is higher than point C, so it has more potential energy than point C.

Answer:

B. The car at point A has more kinetic energy than the car at point C
