Question

define the formula for the variation of mass with its velocity?​

Answer 1

Much of the formalism in special relativity is intimately bound up with Einstein's formula for the variation of mass m with its velocity v, namely m ( v ) = m 0 ∗ [ 1 - ( v / c ) 2 ] - 1 / 2 , where m is the mass, v the velocity, c denotes the speed of light and m 0 ∗ denotes the rest mass, noting that in these papers, ...
