The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D. A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A.
