A 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. Which statement correctly describes the potential energy and the kinetic energy of the bicycle rider?
As the rider moves up the hill, her kinetic energy increases, and her potential energy decreases.
As the rider reaches the bottom of the hill, her kinetic energy and her potential energy decrease.
When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.
When the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.
