Discussion
A car placed on the top of a hill, a compressed spring, and a bent bow are all examples of which energy?
Answer: D
A car on top of a hill, a compressed spring and a bent bow all store energy because of their position or condition, and that is potential energy. It turns to kinetic energy when the car rolls down or the spring and bow are released.
Kinetic energy is the energy of motion and the car is not moving, and chemical energy is stored in fuel and food. Mechanical energy is the sum of potential and kinetic energy, so it is not the specific name for stored energy of this kind.
