Relativistic Mass

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.


Relativistic Mass formula

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


 Units English Metric
\(\large{ m_r }\) = relativistic mass \(\large{ lbm}\)  \(\large{ kg}\) 
\(\large{ m }\) = rest mass \(\large{ lbm}\) \(\large{ kg}\)
\(\large{ c }\) = speed of light \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ v }\) = velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
