	Rest mass energy is the energy an object has when is ~~not~~ moving nor is it in a potential field. The famous equation		Rest mass energy is the energy an object has when is neither moving nor is it in a potential field. The famous equation
			::<math> E=mc^2</math>
			demonstrates the mass energy equivalence where
			::''E'' is the internal energy in joules
			::''m'' is the mass in kilograms
			::''c'' is the speed of light in a vacuum (approximately <math>3.00 \times 10^{8} {\rm \ m/s}</math>)

	~~<math> E=mc^2</math>~~		This relationship was shown by Albert Einstein in 1905.[[File:Albert Einstein Head.jpeg\|200px\|thumb\|right\|Albert Einstein in 1947]]

	~~demonstrates the mass energy equivalence. What this equation means is that the Internal Energy (E) in Joules is~~
	~~equal to the mass (m) in kilograms times the speed of light in a vacuum (c) in meters per second squared.~~

	This ~~incredible~~ relationship was shown by Albert Einstein in 1905.[[File:Albert Einstein Head.jpeg\|200px\|thumb\|right\|Albert Einstein in 1947]]
