| kinetic energy | the energy of motion. The motion of waves, electrons, atoms, molecules, and substances. |
| potential energy | stored energy or energy an object has due to its position (gravitational). |
| sound energy | energy of vibrations, carried by air, water or other matter. |
| radiant energy | electromagnetic energy that travels in transverse waves through empty space. Solar energy is an example. |
| stored mechanical energy | energy stored in objects by the applications of force. Compressed springs and rubber bands are examples. |
| nuclear energy | energy stored in the nucleus. of an atom - the energy that holds the nucleus together. The nucleus of a uranium atom is an example. |
| efficiency | the amount of useful energy you get from a system. |
| thermal energy | is the heat or internal energy in substances - the vibration or movement of atoms and molecules in substances. Geothermal is an example. |
| electrical energy | movement of electrons. Lightning and electricity are examples. |
| motion | is the movement of a substance from one place to another. Wind and hydropower are examples. |
| gravitational energy | the energy of place or position. Water in a reservoir behind a hydropower dam is an example. |
| law of conservation of energy | energy is neither created nor destroyed. Energy doesn't disappear, it just changes form |
| chemical energy | is the energy stored in the bonds of atoms. Biomass, petroleum, natural gas, propane, and coal are examples. |
