Within the framework of this course students gain the knowledge of selected parts of classical physics and dynamics of the physical systems. The introductory part of the course deals with the mass particle kinematics; dynamics, with the system of mass particles and rigid bodies. The students should be able to solve basic problems dealing with the description of mechanical systems. The introduction to the dynamics of the systems will allow to the students deeper understanding as well as analysis of these systems. The attention will be devoted namely to the application of the mathematical apparatus to the solution of real physical problems. Apart of this, the knowledge gained in this course will help to the students in the study of other disciplines, which they will meet during their further studies.

Course outlines:

1. Units, system of units. Physical fields. Reference frames.
2. Particle kinematics (rectilinear motion, circular motion, motion in three dimensions.
3. Newton?s laws, inertial and non-inertial reference frames. Equations of motion in inertial and non-inertial reference frames.
4. Work, power, conservative fields, kinetic and potential energy. Conservation of mechanical energy law.
5. Newton´s law of universal gravitation, gravitational field of the system of n particles and extended bodies. Gravitational field intensity, potential.
6. Gravitational field outside and inside a spherical mass shell and homogeneous mass sphere.
