Book represents a concise presentation of dynamics of particles and bodies and has an intention to explain phenomena due to motion in the most simple and comprehensible manner. Mathematics is reduced to a rational gauge not to ballast the text. Book contains: dynamics of a particle and system of particles and rigid body dynamics. Starting with Newton's laws, free and constraint motion, relative motion, motion in the field of central force are considered. As a special problem, dynamics of mass variable system is read. In rigid body motion: translation, rotation around a fixed axle and fixed...
