Shawn E. McCandless MD,Suzanne B. Cassidy MDWe introduce the concepts of work, kinetic energy, and potential energy in a general setting. The fundamental importance of these concepts arise from the fact that they permit a formulation of a conservation law for mechanical energy.

,Newton’s Five Laws,As mentioned, we will here assume some knowledge of elementary mechanics and the concepts within that theory. As the reader progresses through the book, he or she will find these concepts treated in substantial detail.

Gravitational and Inertial Mass,Since the time of Galileo’s famous experiments with freely falling bodies it has been known that all material bodies, at the same place on Earth, fall with the same acceleration when air resistance is disregarded. Through many experiments this has become a well documented experimental fact.
