| Term | Definition |
|---|---|
| law of conservation of energy | the law that states that energy cannot be created or destroyed but can be changed from one form to another |
| energy | the capacity to do work |
| work | the transfer of energy to an object by using a force that causes the object to move in the direction of the force |
| kinetic energy | the energy of an object that is due to the object´s motion |
| potential energy | the energy that an object has because of the position, shape, or condition of the object |
| mechanical energy | the amount of work an object can do because of the object´s kinetic and potential energies |
| thermal energy | the kinetic energy of a substance´s atom |
| heat | the energy transferred between objects that are at different temperatures |
| chemical energy | the energy that is stored in chemical bonds |
| electrical energy | the energy that results from the flow of moving charges |
| electromagnetic energy | energy resulting from the motion of the charged particles within atoms |
| sound energy | energy given off by a vibrating object |
| nuclear fission | the splitting of the nucleus of a large atom to two or more fragments; releases additional neutrons and energy |
| nuclear fusion | the combination of the nuclei of small atoms to form a larger nucleus; releases energy |
| temperature | a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles of an object |
| conduction | the transfer of heat by direct contact of particles |
| convection | the transfer of thermal energy by the circulation of movement of a liquid or a gas |
| radiation | the transfer of energy as electromagnetic waves |
