| energy | ability to cause change |
| kinetic energy | energy in the form of motion |
| potential energy | stored energy |
| work | the transfer of energy through motion |
| mechanical energy | total amount of kinetic energy and potential energy is a system |
| law of conservation of energy | energy can change form but cannot be destroyed under ordinary conditions |
| temperature | a measure of the average kinetic energy |
| thermal energy | the total energy of the particles in a material. |
| heat | the thermal energy that flows from something with a higher temperature to something with a lower temperature. |
| thermal pollution | occurs when waste heat changes the conditions of the environment |
| specific heat | the amount of energy it takes to raise the temperature of material. |
