General Physics (Mechanics and Electro-Magnetism)

Aim of the course

The course is designed to equip students with the fundamental ideas of physics, starting from the concepts of physical quantity and unit of measurement. The first part of the course deals with material point mechanics (kinematics, statics and dynamics), including notes on rigid body mechanics, while the second part develop the theory of electromagnetism, up until the concept of electromagnetic waves. For all topics, students will be required to solve simple application exercises, in addition to learning the theory.

Examinations

There will be intermediate written progress tests, with an additional oral evaluation in the case of borderline results.

Students who do not pass all the progress tests will be required to sit a written exam on the full course programme, which may be followed by an oral evaluation.
