摘要

This chapter describes the principle of work and energy and the law of conservation of energy for the treatment of the motion of a point mass. Based on a general definition of the concept of mechanical work, the principle of work and energy and the law of conservation of energy are introduced, whereby a distinction must be made between forces with potential and forces without potential.
