| A | B |
| Energy | abilty to cause change and do work |
| Kinetic energy | energy in motion |
| Potential energy | energy that is stored due to position and condition |
| Law of conservation of energy | energy cannot be created or destroyed |
| Thermal energy | moves from one object to another as heat |
| Heat | energy transfer due to a difference in temerature |
| Radiation | energy that travels by waves |
| Conduction | transfer of thermal energy from partical to partical (touching) |
| Convection | transfer of thermal energy that happens when particals move (air movement) |
| Chemical energy | energy stored within chemical bonds |
| Nuclear energy | energy stored in the nucleus and given off when the nucleus splits |
| Electrical energy | the movement of electrons |
