Abstract
In general in physics and particularly in mechanics the concepts of work and energy play an important role that can be traced even in the works of Aristotle. Work and energy are invariant quantities since they do not depend on the choice of coordinate system. In addition, many fundamental laws of mechanics can be expressed in two ways: first by the requirement that certain differential equations are satisfied (for example, in the equilibrium state of an elastic body the differential equations (1.3-10) hold) or by the requirement that a specific quantity in a given state (motion or equilibrium) is in minimum. The second approach comprises what is called the variational methods of mechanics. In this method work and energy are of fundamental importance.
