What happens to kinetic energy as the car goes up the hill? - CORRECT ANSWER-It
decreases

Draw conclusions: How are potential energy, kinetic energy, and total energy related? -
CORRECT ANSWER-While the potential energy of an object decreases the kinetic
energy increases and vice versa. The total energy of the object remains constant.
