Which of these correctly describes the gravitational potential energy and the kinetic motion energy of the bicycle rider?
When the rider is at the top of the hill, her potential energy is the greatest and 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 rides down to the bottom of the hill, her kinetic and her potential energy decrease.
