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.
Conservation of energy means that
energy can be created but not destroyed
energy can be destroyed but not created
energy can be both created and destroyed
energy can be neither created nor destroyed
Kinetic energy can be described as
energy in motion
stored energy
a chemical reaction
connected energy
