This book suppose to give a general view on dynamics as a part of mechanics. It shows the theory of dynamics in the light of examples and exercises connected to the topic. It deals with the dynamics of mass point, system of mass points, rigid body and the system of rigid bodies in various kind of motion. Book follows the main dynamic topics from the dynamic of mass point, through the system of particles, ends with the system of rigid body. The motion of free point and tied point was demonstrated at the beginning, translated motion, rotation and several types of oscillations, too. Each theoretical topic is demonstrated in a practical way on one example of average difficulty (in terms of University studies). The book is divided into the two parts. Part A deals with dynamic theory and general applications. Part B consists of eighteen extra exercises computed in general way. This publication uses the knowledge from specialized classic publications, university web sites, from own experiences in teaching of the University courses on technical sciences including kinematics, dynamics, hydromechanics and thermomechanics
