A comparison of kinetic and potential energy is shown here with the position and motion of a round object with regards to a hill.
Which statements support the claim that an energy transfer is occurring as the ball rolls down the hill? Select ALL that apply.
A) the ball transfers energy to the air in the form of sound
B) the ball generates a gravitational field as it rolls downward
C)the potential energy is converted to kinetic energy as the ball rolls down the hill
D)the kinetic energy is converted to potential energy as the ball rolls down the hill
E) the ball loses kinetic energy but generates thermal energy as it moves down the hill
