Finalità

The aim of the course is to give to the student an organic knowledge of the fundamental laws of classical mechanics (elementary dynamics and rigid bodies, short account of fluids) and the main principles of thermodynamics and electrostatics; the student should become able to solve in an autonomous way simple problems .

Attività d'esercitazione

Practical exercises, consisting in the solution of simple problems whose text was previously assigned.

Modalità d'esame

The examination consists in a written and an oral test. The written examination can also be taken in form of a few written tests proposed during the development of the course.

Propedeuticità

The knowledge of the elementary matematics and of the differential and integral calculation is recommended, therefore the courses of Analisi Matematica AB e Geometria should be previously attended.
