"Lec 15 - Four-Vector in Relativity" Fundamentals of Physics (PHYS 200) The discussion of four-vector in relativity continues but this time the focus is on the energy-momentum of a particle. The invariance of the energy-momentum four-vector is due to the fact that rest mass of a particle is invariant under coordinate transformations. 00:00 - Chapter 1.
