energy |
the ability to do work |
|
work |
the transfer of energy to an object by the application of a force that causes the object to move in the direction of the force |
|
kinetic energy |
energy of motion |
|
potential energy |
the energy an object has because of its position; stored energy |
|
thermal energy |
a form of kinetic energy due to the movement and vibration of the particles in an object; heat energy |
|
mechanical energy |
energy associated with the motion and position of an object |
|
electrical energy |
a form of energy created by the movement of electrons |
|
chemical energy |
the energy stored in the chemical bonds that hold compounds together |
|
sound energy |
is the movement of energy through substances in longitudinal waves; produced when a force causes an object or substance to vibrate — the energy is transferred through the substance in a wave |
|
radiant energy |
energy that travels in the form of waves, especially electromagnetic waves |
|
nuclear energy |
energy that is stored in the nucleus of an atom; the energy that holds the nucleus together |
|
Law of Conservation of Energy |
Energy cannot be created or destroyed. |
|
ME FORMULA |
PE + KE |
|
fission |
the process by which the nucleus splits into two or more fragments and releases neutrons and energy |
|
fusion |
the process in which light nuclei combine at extremely high temperatures, forming heavier nuclei and releasing energy |
|
GPE |
gravitational potential energy; potential energy of an object that depends on its vertical position and mass |
