Anotace:

Within the framework of this course the students gain the knowledge of selected parts of physics. The introductory part of the course deals with the classical mechanics, which involves the particle kinematics; dynamics of the mass particle, system of mass particles and rigid bodies. The students should be able to solve basic problems dealing with the description of mechanical systems. The classical mechanics is followed by quantum mechanics, band theory of solids and special theory of relativity. The students can use the facts gained in this course in the study of other obligatory courses namely the theory of radioelecronic elements. 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.
