Kinetic energy: the energy of a moving object.


Potential energy: energy that is stored in an object or material.

Temperature: the average kinetic energy of the molecules in a material.



Heat: energy that flows between objects that have different temperatures.


Radiation: the transfer of energy by electromagnetic waves.



Conduction: the transfer of energy by direct contact of molecules.



Convection: the transfer of energy by the flow of a liquid or gas. 



Insulation: prevents heat from flowing in or out of a material.
