The bicycle rider is traveling up a hill. When the rider reaches the top of the hill, she stops to rest. Then she travels down the hill. The diagram shows the rider in the three different positions. Which of these correctly describes the potential energy and the kinetic energy of the bicycle rider?
When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.
As the rider moves up the hill, her kinetic energy increases, and her potential energy decreases.
When the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.
As the rider reaches the bottom of the hill, her kinetic energy and her potential energy decrease.
