#### Training objectives

- The objectives of the course are supplying solid knowledge and mastering of the treated topics. The acquired knowledge will enable the student to profitably understand and make the most of successive courses that build upon this one.

The course goes through the following main topics: mechanics for a point mass (both kinematics and dynamics), for a system of particles and rigid bodies in particular, dynamics of fluids at a basic level, acoustics, heat and thermodynamics.

The student will be supplied with the formal rigour and will show their abilities in properly formulating and addressing problems concerning the treated subjects. #### Prerequisites

- Robust knowledge of elementary mathematics and algebra, trigonometry and analytic geometry is advisable. Basic knowledge of calculus is an asset.
#### Course programme

- Main topics: Scientific method and vectors (8 hours). Kinematics and dynamics of the point mass (20 hours). Laws of forces (14 hours). Dynamics of systems of particles (16 hours). Particle collisions (6 hours). Oscillations and waves (14 hours). Dynamics of fluids (12 hours). Thermodynamics (30 hours).

Detailed topics: Measures and units of measure, vectors and laws of forces. Kinematics of the point mass and relative motion. Dynamics of the point mass and of systems of particles. Dynamics of rigid bodies. Work and energy. Gravitation and the gravitational field. Particle collisions. Oscillations and waves. Acoustic waves, principle of superposition and stationary waves. Fluidodynamics. Thermal equilibrium, head and temperature. Kinetic theory of gases. Ideal gases and real gases. First and second law of thermodynamics. Thermal machines and Carnot cycle. Reversibility and irreversibility in thermodynamics. #### Didactic methods

- All the topics are presented during classes within the due amount of time, going through the mathematical and physical nitty-gritty of the principles, equations and theorems, step by step at the blackboard, discussing all the relevant details. Students are continuously solicited to stop the teacher and ask questions. The same holds true for the classes devoted to exercise and problem solving.

All the material used by the teacher during classes (both theory and exercises) is available on the web before being discussed and presented. This is done on purpose, to motivate them to have a look beforehands, and come up with well thought-out questions during classes. #### Learning assessment procedures

- Written exam: either two partial exams, or one single exam.

Oral exam: following successful written exam.

The (successful) couple of partial exams is equivalent to the single one. To sustain the oral exam the student is expected to pass either both partial exams, or the final single one.

Every written exam consists of three/four exercises with a total amount of available time of three hours. There are total thirty-six available points, which are evaluated over thirty. Collecting more than thirty points is equivalent to passing with flying colours.

The duration of the oral exams is in the range 20-40 minutes for those who passed the partial written exams, 45-60 otherwise.

The final mark is the simple average of the written and of the oral exams.

Upon a successful written exam the student is eligible to sustain the oral exam until the end of the current academic year.

While the written exam has been conceived to essentially assess the abilities of the student in properly formulating, addressing and solving problems by applying the laws of physics in a self consistent and correct way, the oral exam aims at assessing the expertise acquired by the student, their

ability to establish connections between the different topics and aspects of the course, as well as the formal mathematical rigour demanded by each topic. #### Reference texts
