The book describes the mechanics of all kinds of movements, invariably found in the theory and practice of complex machines, ships and aircraft, rockets and spacecraft, the movement of bodies relative to the Earth and in the explanation of natural phenomena. A strict distinction is made between the forces of the physical , creating accelerations relative to the coordinate system (non-rotating,) with the beginning at the center of the solar system's mass), and inertial forces , As a dalamber , and due to the choice of a mobile coordinate system - Euler (portable and coriolis) inertial forces. A purely analytical conclusion of the basic formulas of kinematics of a point and an absolutely solid body is given, accompanied by a statement of the basics of vector and tensor analysis in the minimum necessary volume. Along with the presentation of the initial positions of classical mechanics, examples of the compilation of equations and the analysis of solutions to the problems of dynamics and relative motion of various difficulties with a large number of explanatory figures are given.
