A toy car is rolled up and over a hill. The diagram shows the toy car at three different positions. Which statement best describes the potential and kinetic energy of the toy car?

• When the toy car is at the bottom of the hill, the potential energy is the greatest and kinetic energy is the least.

• At the top of the hill, the toy car has the least potential energy and greatest kinetic energy.

• As the car moves up the hill, the potential energy increases and kinetic energy decreases.

• As the toy car moves down the hill, the potential energy increases and kinetic energy decreases.
