Description
The Lagrangian formulation is a powerful method in classical mechanics used to describe the motion of a system. It focuses on the difference between the kinetic and potential energies of a system, expressed through the Lagrangian function, L=T−V , where is the kinetic energy and is the potential energy. The equations of motion are derived using the principle of least action, leading to the Euler-Lagrange equations. This formulation is particularly useful for systems with constraints and in cases where generalized coordinates are more convenient than traditional Newtonian methods.
