Question: Q: Energy constantly changes back and forth between kinetic and what type of energy?   Read this paragraph and choose the correct option from the provided answers:  Energy also constantly changes back and forth between kinetic and potential energy. Kinetic energy is the energy of movement. For example, a ball falling through the air has kinetic energy because it is moving ( Figure below ). The random motion of molecules is due to kinetic energy, and the driving force behind diffusion.   Choices:  - practical  - physical  - mechanical  - potential   A:
Answer:
potential
