E = m*c2 E is energy. m is mass. c is the speed of light.
The letter 'c' in that equation represents the speed of light.
'c' represents the speed of light.
E represents energy, m represents mass, and c² is a very large number, the square of the speed of light.
E=MC2The E represents the units of energyThe M represents the units of massThe C Represents the Speed of LightE=MC2 means Energy equals mass times the speed of light squared. Although this is not 100% correct it is very close!
