Course detail

# Physics

FSI-BFAcad. year: 2019/2020

It is an introductory course of classical physics for bachelors, which is oriented to solving simple physical and technical tasks. The acquired knowledge creates the physical basis of technical branches. The course covers: Motion of a particle (velocity, acceleration); Work and energy (conservative and non-conservative forces, potential); Dynamics of a rotating solid body; Vibrations, harmonic oscillator; Waves, travelling wave, interference of waves; Thermodynamics; Electrostatic field, electric current, simple circuit.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

In order to get a credit students must acquire at least 50% rating in both the seminars and the labs. The exam has written (possibly also oral) form and it tests the knowledge of physical quantities, laws and mainly their application in practise. The classification depends on acquired amount of points:

A: 90 - 100

B: 80 - 90)

C: 70 - 80)

D: 60 - 70)

E: 50 - 60)

F: 0 - 50)
