Code: G250B-
Teacher:  Claudio Grillo
CFU subdivision: Lectures: 4
Practices in classroom: 2
Basic aims:  The aim of the course is to provide the mechanics and heat
transfer fundamentals
Acquired skills:  knowledge for the interpretation of physical phenomena.
Ability to resolve numerical exercises applied to real world
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.
