WebJun 28, 2024 · A Lorentz-invariant formulation of Hamiltonian mechanics can be developed that is built upon the extended Lagrangian formalism assuming that the Hamiltonian and Lagrangian are related by a Legendre transformation. That is, H(q, p, t) = n ∑ μ = 1pμ∂qμ ∂t − L(q, ∂q ∂t, t) where the generalized momentum is defined by. pμ = ∂L ∂ ... WebIt arises naturally from them, as Lagrangian is a formalism of classical mechanics that can explain the behavior of physical systems both in their translations and rotations. For instance, consider a simple pendulum. It's only degree of freedom is ϕ, the angle denoting its deviation from the vertical.
