WebbThe Stationary Action Principle Lagrangian and Hamiltonian Dynamics Oxford Academic Abstract. This crucial chapter focuses on the stationary action principle. It introduces Lagrangian mechanics, using first-order variational calculus to derive WebbIn other words, the action satisfies a variational principle: the principle of stationary action (see also below). The action is defined by an integral, and the classical equations of motion of a system can be derived by minimizing the value of that integral.
