Lagrangian Formulation of Mechanics for Single Particles
The Lagrangian formulation of mechanics represents a variational approach to classical dynamics that redefines physical laws through the stationary action principle rather than Newton's vector forces. It employs generalized coordinates and time-independent scalar functions known as the Lagrangian, defined specifically as the difference between kinetic and potential energy ($L = T - V$). This framework constitutes the foundational formalism of analytical mechanics, enabling a coordinate-invariant description of particle trajectories within conservative systems.
