| Mechanical Energy | Anything that move or has the potential to move |
| Energy | The ability to do work |
| Six forms of energy | radiant, chemical, mechanical, thermal, nuclear,electrical |
| Radiant Energy | Energy of high frequency electromagnetic waves |
| Fusion | Nuclear energy roduced by combining atoms |
| Electrical Energy | Movement of electrons along a conductor |
| Kinetic Energy | Energy of motion |
| Rotatory Motion | Helps to convert natural mechanical energy |
| Chemical Energy | Energy that is released by oxidation, reduction and digestion |
| Direct Combustion | Most common method of thermochemical conversion |
| Thermal Energy | Produced by rapid atomic vibration |
| Energy from hot objects | Radiant energy |
| Nuclear Energy | Involves splitting atoms of hydrogen or uranium |
| Potential Energy | Stored energy |
| First Law of Energy Conservation | Law that states that energy cannot be created or destroyed |
| Efficiency | A measure of how well energy is converted |
| Battery | Converts chemical to electrical energy |
| Natural gas | Not a renewable energy source |
