What type of potential energy is caused by restorative forces?

• nuclear potential energy

• elastic potential energy

• electric potential energy

• magnetic potential energy

A cyclist has 5500 J of gravitational potential energy at the top of a hill. After riding down the hill, the cyclist has 5700 J of kinetic energy. What can cause the cyclist to have more kinetic energy than the initial potential energy?

• Wind resistance added kinetic energy when going downhill.

• The increase of heat produced by the tires added more kinetic energy.

• The cyclist added more energy by pedaling downhill.

• The amount of gravitational force was less at the top of the hill.
