I wonder what's the precise meaning of Einstein's formula for energy of a particle [tex]\frac{m c^2}{\sqrt{1-\frac{v^2}{c^2}}} [/tex]. Is it total energy of particle (considering potential energy)? If it is then if we move (infinitesimally slowly) the particle from area of low potential to high its mass will increase. So the inertial mass is changing.(adsbygoogle = window.adsbygoogle || []).push({});
