| energy that is stored due to an object's position | potential energy |
| states that energy cannot be created or destroyed but only changes form | law of conservation of energy |
| measure of the average kinetic energy of the atoms in an object | temperature |
| transfer of energy from one object to another due to a difference in temperature | heat |
| transfer of energy by collisions between the atoms in a material | conduction |
| transfer of heat that occurs when particles move between regions of different temperatures | convection |
| energy that is transferred by waves | radiation |
| chemical reaction that absorbs heat energy | endothermic reaction |
| chemical reaction that releases heat energy | exothermic reaction |
| substance that changes the rate of a chemical reaction without changing its own structure | catalyst |
