Introduction to Lagrangian Mechanics
(1) Newtons method is just as fundamental as Lagrangian, and
in some cases, has wider range of application. However it is
cumbersome to use for problem solving.

LAGRANGIAN MECHANICS
13.1 Introduction
The usual way of using newtonian mechanics to solve a problem in dynamics is first of
all to draw a large, clear diagram of the system, using a rule
