The book consists of two parts: (1) classical mechanics and (2) relativistic mechanics. In the first part the laws of mechanics are treated in the Newtonian approximation i.e. when motion velocities are much less than the velocity of light, while in the second part of the book velocities comparable to that of light are considered.

Each chapter opens with a theoretical essay followed by a number of the most instructive and interesting examples and problems, with solutions provided. There are about 80 problems altogether; being closely associated with the introductory text, they develop and supplement it and therefore their examination is of equal inportance.

A few corrections and refinements have been made in the present edition to stress the physical essence of the problems studied. This holds true primarily for Newton’s second law and the conservation laws. Some new examples and problems have been provided.
