| Term | Definition |
|---|---|
| Mass Energy | the largest potential source of energy in the world |
| Mechanical Energy | energy of an object due to its physical position |
| Chemical Energy | potential energy stored in chemical bonds |
| Electrical Energy | field forces acting on other electrical charges that can do work |
| Magnetic Energy | the ability to do work through the influence of a magnetic field |
| Thermal Energy | the sum of kinetic energies of all the particles in an object |
| Nuclear Energy | released when protons and neutrons in nuclei are separated or combined |
| Acoustic Energy | transmission of energy through matter by the periodic motion of particles |
| Radiant Energy | energy that can be transmitted through a vacuum |
