Assume that a person bouncing a ball represents a closed system. Which statement best describes how the amounts of the ball's potential and kinetic
energy change?
O A. The ball's kinetic energy increases as it falls and its potential
energy decreases.
B. The ball's potential energy decreases as it rises and its kinetic
energy increases.
C. Both the kinetic and potential energy of the ball decrease.
D. Both the kinetic and potential energy of the ball increase
