the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
