chp3 4 (2) In general mechanics, the Lagrange equations are equations used in the study of the motion of a mechanical system in which independent parameters, called generalized coordinates, are selected as the variables that determine the position of the system. These equations were first obtained by J. Lagrange in 1760. 1) Lagrangian equations of motion of isolated particle(s) For an isolated non-relativistic particle, the Lagrangian is a function of position of the particle (q(t)), the velocity of the particle (q’ = ∂q/∂t) and time (t).

As final result, all of them provide sets of equivalent equations, but their mathematical description differs with respect to their eligibility for computation and their ability to give insights into the The Hamilton–Jacobi equation is particularly useful in identifying conserved quantities for mechanical systems, which may be possible even when the mechanical problem itself cannot be solved completely.
