Code Course name G260C- Physics CFU Year 6 1 Teacher Francesco Broggi Basic aims The aim of the course is to provide the necessary basis for the understanding of the main physical phenomena of general interest, with particular focus on subjects linked to other Degree courses. Acquired skills The student acquires basic knowledge necessary for the understanding and interpretation of main physical phenomena, in particular in the field mechanics, fluid dynamics, thermodynamics and light-matter interaction. Course contents After a short mathematical review, the fundamental concepts and working tools of Physics (dimensions and units, scalars and vectors) are introduced. The basic laws of kinematics with main examples of motion are described, followed by the fundamental laws of dynamics . The laws of statics and dynamics of perfect fluids and the kinetic theory of gases are described. The main concepts of thermodynamics are introduced, and the main thermodynamic transformations are described. Finally, the main concepts of electricity, magnetism with an overview of the Maxwell equations are illustrated. The electromagnetic nature of light is described together with the fundamental laws of its interactions with the matter; environmental radioactivity together with the Radon pollution problem are introduced.
