Lagrangian function

Lagrangian function

A function of the generalized coordinates and velocities of a dynamical system from which the equations of motion in Lagrange's form can be derived. The Lagrangian function is denoted by L(q1, …, qf; ˙q1, …, ˙qf; t). For systems in which the forces are derivable from a potential energy V, if the kinetic energy is T, the equation below holds. See Lagrange's equations
