At its heart, Lagrangian mechanics is a reformulation of classical mechanics based on the . Instead of tracking every individual vector force (like ), we look at the energy of the system. The fundamental equation is the Lagrangian ( ) : L=T−Vcap L equals cap T minus cap V is the Kinetic Energy. is the Potential Energy. Here are known, reliable sources (search the titles

A uniform disk of mass ( m ) and radius ( R ) rolls without slipping down an inclined plane of angle ( \alpha ). Use the distance along the incline as the generalized coordinate. Show that the acceleration is ( \frac23g\sin\alpha ) (moment of inertia ( I = \frac12mR^2 )). The fundamental equation is the Lagrangian ( )
