The course aims to convey fundamental concepts of General Physics, i.e. physical quantities and unity of measurements, basics of mechanics, fluid dynamics, thermology and electricity, diffusion in gas and solutions, with corresponding medical applications.

Basic mathematics. Skills in differential computation are not required.

Lectures with projection of power point slides. Physics exercises executed in real time displayed on a whiteboard.Videoconference link to peripheral sites. .

8 hours of physics exercises are in addition to the course.

Written exam with multiple choice questions.
