Relativistic Mass

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Relativistic mass, abbreviated as \(m_r\), refers to the mass of a body which changes with the speed of the body as this speed approaches close to the speed of light.

 

Formulas that use Relativistic Mass

\(\large{ m_r =  \frac { m}  {  \sqrt { \frac {1 \;-\; v^2} {c^2} } } }\)   

Where:

\(\large{ m_r }\) = relativistic mass

\(\large{ m }\) = rest mass

\(\large{ c }\) = speed of light

\(\large{ v }\) = velocity
