Definitions:

Energy Form

Different manifestations of energy, such as kinetic energy, potential energy, thermal energy, electrical energy, chemical energy, and nuclear energy.

Mass-Energy Transfer

The concept that mass and energy are interchangeable, underpinning the principle of mass-energy equivalence.
