What are Four-Vectors in Einstein's Special Relativity? Definition and examples | @PhysicsNextBook

Описание: In this video we discuss four-vectors in Einstein's Special Relativity. How four-vectors are defined in Special Relativity is explained using the Lorentz transformation equations. We provide three basic examples of four-vectors which are spacetime coordinate differential, velocity four-vector or four-velocity and momentum four-vector or four-momentum and also explain why they behave as four-vectors.
