Traditional at the whiteboard and with slides.
Mechanics of the material point, of the systems of material points, of fluids, thermodynamics. Electromagnetic phenomena, optical instruments
The course will provide the basic knowledge required for the comprehension of fundamental physical processes. In particular, the course will focus on the mechanics of solids and fluids, on electromagnetic phenomena and the optics. The student will have the tools to face subjects increasing in complexity in other exams of the Degree Course, by means of an improved knowledge on mechanical interactions among bodies, energies, dinamycal aspects due to elastic forces, collisions, thermodyamincs, dynamical properties of fluids, electrical processes, light and instruments such as the microscope
Discuss the methods to correctly perform force analysis in simple mechanical systems, apply conservation laws to an appropriate physical system, understand the concept of field and its use for the description of physical phenomena, and correctly use the units of measurement of physical quantities and knowledge of conversion factors between homogeneous units of measurement

The learning assessment includes a written test and an oral test.
Written test: consists of three numerical problems and two theoretical questions. The sufficiency in the resolution of the exercises is mandatory for passing the written test. The evaluation of the remaining theoretical questions will be done only in case of sufficient resolution of the problems.
Oral exam: in case of a positive outcome both of the resolution of the problems and of the answers to the theoretical questions, the oral exam will consist of a discussion on the paper. In case of failure to pass the theoretical questions the oral exam will consist of three questions on the whole program.
