Abstract

In preceding chapters we used Lagrange’s equations principally to formulate problems, not to determine the motion of physical systems. In that formulation the generalized forces occurred merely as the symbols Q s (s = 1, 2, …, n); they were, in general, functions of all coordinates, of their time derivatives, and of time or perhaps they arose as partial derivatives of a potential function, but the precise functional form of the Q s or of the potential energy V was of no importance in the formulation. However, when one wants to solve the equations of motion, the forces must be specified; in fact, the problem is not fully described until the forces are given.
