Energy
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 an substance's atoms |
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 energy | the energy stored in the nucleus of an atom as a result of strong nuclear forces |
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 |
conduction | the transfer of thermal energy by the circulation of movement of a liquid or a gas |
radiation | the transfer of energy as electromagnetic waves |
