| energy | ability to cause change; can affect the temperature, speed, shape, or direction of an object |
| kinetic energy | energy of motion; is influenced by an object's mass and speed and can be transferred from one object to another when objects collide |
| potential energy | energy that is stored and that comes from an object's position or condition |
| law of conservation of energy | states that energy cannot be created or destroyed but only transformed from one form to another |
| temperature | measure of the average kinetic energy of the particles in any object; the greater the average kinetic energy, the higher the object's temperature |
| thermal energy | total amount of kinetic energy of the particles in a material |
| heat | energy transfer due to a difference in temperature |
| radiation | energy that travels by waves in all directions from its source |
| conduction | transfer of thermal energy from particle to particle through a material when there is a temperature difference |
| convection | transfer of thermal energy that happens when particles move from one place to another where there is a temperature difference |
| chemical energy | energy stored within chemical bonds |
| endothermic reaction | a chemical reaction that absorbs energy |
| exothermic reaction | a chemical reaction that give off energy |
