Wikipedia definition
2. Principle of least actionThis article discusses the history of the principle of least action. For the application, please refer to action (physics). In physics, the principle of least action – or, more accurately, the principle of stationary action – is a variational principle that, when applied to the action of a mechanical system, can be used to obtain the equations of motion for that system. The principle led to the development of the Lagrangian and Hamiltonian formulations of classical mechanics.
