Energy is Equivalent to Mass |

![]() |
Energy and mass are related to each other by the well-known formula E0= mc2, where E0 is the rest energy, m is the mass, and c is the speed of light in vacuum. This means that mass and energy are equivalent. The 'effective' mass M of an object moving relative to an observer at rest is given by
where E is the energy of the object and m is the mass of the object. This formula is called the relativistic mass formula.
