Fundamentals, and time, aim at relating the motion of a body to the forces acting on the body, at each instant of time. Thus these laws express cause (force) and effect (motion) relationships, at each instant of time, and since these relationships are vectorial in nature, this approach is often referred to as ..

Book 1994 mechanics the fundamental laws are expressed in terms of work done and energy exchanged. The extensive use of mathematics is a consequence of the fact that in analytical mechanics problems can be expressed by variational State­ ments, thus giving rise to the employment of variational methods.
