Learning outcomes

At the end of the course the student knows the meaning of the main quantities of classical physics, their units and relative relations. The student knows the concepts of measurement uncertainty and error propagation, the mechanics of single points and of composite systems, the elementary theory of classical electromagnetism in vacuum and in matter. The student has also basic knowledge of geometric and wave optics.

Teaching methods

Lectures and classroom exercises.


Assessment methods

The knowledge of the course topics will be verified by means of a written test with exercises at a level of difficulty similar to those in the textbook and to those solved during lectures. The written test duration is 3 hours.

A grade equal or higher than 15 is required to pass the written test. Students with a grade equal or higher than 24 may ask to confirm the grade as final, waiving the oral test.

Two partial written tests will take place: the first at mid course, regarding mechanics, the second at the end, regarding electromagnetism. The duration of each is 3 hoursStudents with an average grade equal or higher than 18 may ask to confirm the grade as final, waiving the oral test.

The oral test will feature exercises and more theoretical questions.
