The student who enrols in the course should be able to use the Cartesian coordinate system, should operate to solve simple cases of uniform motion and uniformly accelerated motion, Newton's laws and the laws of conservation of energy and momentum. He should be able to describe the basic structure of matter at the atomic level, further to explain the term of the electric charge, the electric current. He should be able to use the basic quantities describing the electric and magnetic fields and to assess the impact of these fields on the movement of electric charge. He should be able to describe the oscillating mechanical harmonic motion and to explain the mechanical progressive wave. He should be able to apply the basic laws of geometrical optics (the laws of reflection and refraction) for solving rays of light propagation. Students should be familiar with the mathematical apparatus at the level of basic work with vectors, differentiation and integration of scalar and vector functions of a scalar argument.
Generally, the knowledge on the technical university bachelor degree level is required.
