description Overview

D'Alembert's principle

D’Alembert’s principle states that the resultant force acting on a system undergoing motion is equal to the time derivative of its momentum.

Lagrangian mechanics

Lagrangian mechanics reformulates classical mechanics by focusing on a system's generalized coordinates and their time derivatives to define a Lagrangian function—the difference between kinetic and potential energy—from which equations of motion are derived.
