# Rest Energy

Written by Jerry Ratzlaff on . Posted in Relativity

Rest mass ( $$m_0$$ ) of a particle is the mass of a partical that is measured at rest with respect to the observer.

### Rest Energy Formula

$$\large{ E_0 = m_0 c^2 }$$

Where:

$$\large{ E_0 }$$ = energy rest mass

$$\large{ m_0 }$$ = rest mass

$$\large{ c }$$  = speed of light
