All three of Newton's law for a wide class of mechanical systems (conservative systems, Lagrangian systems, Hamiltonian systems) are associated with various variational principles mi. In this formulation of classical mechanics of such systems is based on the principle of stationary action.

System move so as to ensure stationarity of the action functional. This formulation is used, for example, in Lagrangian mechanics and Hamiltonian mechanics. The equations of motion in Lagrangian mechanics are the Euler - Lagrange, and Hamilton - Hamilton.
