Prerequisites for admission
Basic algebra; trigonometry; logarithms; functions and their properties; derivative and definite integral (their geometric interpretation and physical meaning)
Teaching methods
The course includes lectures with exercises. The lessons will be carried out with the help of slides.
Teaching Resources
The course does not refer to a specific textbook. Recommended university level texts include, among others:
- Giancoli, "Fisica", or "Fisica con Fisica Moderna"
- Halliday, Resnick, Walker, "Fondamenti di Fisica";
- Jewett, Serway - "Principi di Fisica"
These books are available in university libraries, and are new and used in the library.

Assessment methods and Criteria
Type of exam: the exam includes a written test, with exercises and possibly simple theoretical questions, and an oral interview on the course content. There are two partial tests (ongoing), one about halfway through the course, the other at the end; the passing of which allows direct access to the oral test.
The partial tests will be carried out only in the session of June and July.
During the written tests it is possible to consult the textbook and notes.
The use of mobile phones or media to communicate is absolutely forbidden.
