The Principle of Least Action: Derivation of Newton's Second Law

This video provides an introduction to the principle of least action and shows how Newton's Second Law emerges as a constraint for particle moving in one dimension. This video is inspired by Richard Feynman's lecture on the Principle of Least Action, which I highly recommend.
