Term | Definition |
---|---|
Work | when a force moves an object through a distance |
Force | push or a pull |
Kinetic energy | energy of motion |
Potential energy | stored energy |
Elastic potential energy | the energy of stretching an object |
Gravitational potential energy | the energy due to height or position |
mechanical energy | energy associated with motion. sound is a type of mechanical energy |
thermal energy | a measure of the energy of the particles(atoms) in an object. The faster the particles move, the warmer the object feels |
chemical energy | energy stored in chemical bonds. |
electrical energy | energy carried by flow of an electrical charge |
electromagnetic energy | energy that travels in waves |
nuclear energy | energy stored in the nucleus of an atom. When the nucleus is split, energy is released |
energy conversion | a change from one form of energy to another |
The Law of Conservation of Energy | states that energy cannot be created or destroyed; it changes from one form to another |
