Category:Principle of Least Action

This category contains pages concerning Principle of Least Action:

The Principle of Least Action is a physical law which states the following:

Let $S$ be a dynamical system moving under conservative forces from point $A$ to point $B$.

The motion of $S$ takes place in such a way that the action has a stationary value with respect to all other possible trajectories from $A$ to $B$ with the same kinetic plus potential energy.
