The course provides an introduction to mechanics for students starting their study in physics. It is oriented on fundamentals of the Newton mechanics and involves kinematics and dynamics of mass points and their systems as well as mechanics of rigid bodies. The second part of the course is devoted to the motion if the bodies in different fields of forces.
