| A | B |
| Mechanical energy | Energy of motion or position of an object (can be kinetic or potential) |
| Thermal Energy | also called heat is the movement of the particles of a substance which causes an increase in temperature |
| Electrical Energy | Moving electrons (Examples include power lines, batteries, and lightening) |
| Chemical Energy | Potential energy stored in the bonds of molecues (substances), like in food or gasoline molecules |
| Nuclear energy | A huge amount of energy is stored in the nucleus of an atom - released by fusing or splitting (atomic energy) |
| Radiant Energy | electromagnetic energy, travels in waves (sunlight, x-rays, and radio waves) |
| Law of conservation of energy | states that the amount of energy that exists in the universe always remains the same (can not be created or destroyed) |
| Potential Energy | stored energy |
| Kinetic Energy | energy of motion |
