Language of instruction
The program of the course is oriented to provide a basic understanding of physical phenomena through a variety of topics of classical physics, including mechanics of point particles, electrostatic, electric currents and circuits, magnetism and electromagnetism.
Reference texts
Halliday, Resnick, Walker, "Fondamenti di Fisica", Casa Editrice Ambrosiana
Educational objectives
At the end of the course students will have learned the basic knowledge of classical physics and electromagnetism and will be able to solve simple exercizes on the main topic discussed during the course.
Basic knowledge of algebra, analytic geometry, plane trigonometry, differential and integral calculus.
Teaching methods
Lectures on all the arguments of the course.

Learning verification modality
The exam consists of a written and, eventually, an oral exam. The result of the written test is decisive for admission to the oral test. The oral is required only if you reach a minimum result. In the case of oral examination it is not carried out a strict arithmetic mean between the written test and oral exam. In the written test the student must demonstrate the ability to solve at least two of the three problems assigned. The time assigned to solve the problems is 2-3 hours.
