Learning objectives

At the end of the course, it is expected that the students have acquired:
(1) an organic knowledge of the fundamental laws of classical mechanics (elementary dynamics and rigid bodies, short account of fluids), mechanical waves and the main principles of thermodynamics(Knowledge and understanding);
(2) ability to discuss the fundamental aspects of the covered topics and to set up and solve simple problems on their own (Applying knowledge and understanding);
(3) ability to critically evaluate the results obtained in carrying out the problems, showing also ability to check for errors, eg. across the dimensional calculation, the reasonableness of the result, analytical testing (Making judgments);
(4) ability to expose the concepts acquired in a clear and comprehensive (Communication skills).


The knowledge of the elementary mathematics and of the differential and integral calculation is recommended, therefore the courses of "Mathematical Analysis 1" and "Geometry" should be previously attended.

Course unit content

The course is composed by theoretical lessons and by tutorials on all topics of the course. The topics covered are the following:

1) Classical mechanics: point mass, discrete and continuous systems, rigid body. Kinematics in one and more dimensions.
2) Fluids: statics and dynamics.
3) Priciples of thermometry and calorimetry.
4) Thermodynamics for perfect gases, an introduction to real gases. Thermal machines.

Teaching methods

For each topic were held lectures, by making use of the blackboard and contemporary projection of summary diagrams on the screen. The summary diagrams are preliminarily made available to students via a website, specifically for the course. At the end of each topic, the theoretical lessons are followed by hours spent on exercises, during which problems are solved in an assisted mode. The texts of these exercises are made available to the students in advance through the website of the course, so as to allow students, who wish, to carry out the problems before the tutorials. During the tutorials, for each proposed problem, students have the time to solve it on their own, with the possibility of support on demand; therefore the problem is solved on the blackboard for all, so as to provide a guide to solving the problem and even to the preparation of the written tests. The sequence of hours of lessons and exercises follows a calendar communicated to students at the beginning of the course.

Assessment methods and criteria

The exam consists of a written exam (even in form of in-course written tests) and an oral examination. All the examinations require the development/discussion of some simple problems, the exposure of theoretical concepts and/or the presentation of simple demonstrations. Evaluation criteria: correctness of the problem [40%], completeness of the preparation [30%], critical sense and propriety of language [30%].
