Lecture
This lecture covers the Lorentz covariant formulation of Newtonian mechanics, introducing concepts such as timelike, null, and spacelike 4-vectors, 4-velocity, 4-acceleration, and 4-momentum. It also explores the relativistic version of Newton's second law, F=ma. The instructor provides extra time for answering the question: What is the conserved charge associated with the Lorentz boost symmetry?
