10 CFU - 1° Semester

**Physics**The course aims to provide basic knowledge to understand physical concepts and methods currently applied to medicine. In particular, the student will be acquainted about some basic physical laws, useful to understand the physiological processes and will learn basic concepts useful in the proper use of the equipment used at work.

As prerequisite a basic knowledge of classical physics, algebra, Euclidean geometry and trigonometry are required.
