Annotation
The Principles of Physics I is the opening course of physics series in the program Science. It provides a general introduction to the Physics as an essential pillar of natural sciences, and further focuses on concepts of classical mechanics with outreach to complex phenomena in chemistry and biology. The course set the knowledge base for all follow-up classes in physics. Also, it provides a guide to application of the mechanics and acoustics across the natural sciences.

Course completion requirements

The condition for completing the course is the successful passing of the exam, which is preceded by getting credit for the exercises. The exam itself is generally oral, but the solution - or outline of the solution - of a specific example can be one of the points discussed at the exam.

Requirements to the exam

Final mark is based on the oral examination. Oral examination takes place during the examination period and students must first obtain the credit for practical exercises. Credit for exercises is based on the solution of take-home problems (30%), two tests (midterm and final, each 30%) and acivity during the exercises (10%).
