- The energy equivalent to the given mass. [Units: Joules, J]
- The mass of an object or particle. [Units: Kilogram, kg]
- The speed of light [Value: 3 x 108 m s-1]
What it means
This equation gives the amount of energy equivalent to a certain mass and is a result derived from Einstein's theory of relativity. In any reaction if the final products have lower mass than the initial state, then the difference in mass is released as energy, with an amount given by the above equivalence relation.
