【Abstract】 The equation of motion for a particle is derived from the Hamilton’s principle in a covariant vector form and the generalized momentum for a relativistic particle is given. It also discusses the Hamiltonian for the particle in an electromagnetic field, and points out some improprieties in [1].更多还原
