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:
potential
