Relativistic mass vs Rest mass in Einstein's Special theory of Relativity | @PhysicsNextBook

Описание: In this video we shall go over the idea of velocity-dependent mass or Relativistic mass. What it is, how it differs from the Standard or Ordinary mass - also called the Rest mass or the invariant mass, where the idea of a relativistic mass come from ... and finally why one should not consider the Relativistic mass as a very good concept at the fundamental level.
