## Learning Objectives

• knowledge and understanding: knowledge of the fundamentals of Mechanics and Thermodynamics, and understanding their mathematical description.
• applying knowledge and understanding: developing and improving the ability in recognizing the Physics laws which govern a phenomenon and the use of the suitable techniques in order to solve problems.
• making judgments: good ability to estimate the order of magnitude of quantities which describe a phenomenon, and awareness of the degree of importance of a Physics law (e.g. a conservation law, a universal law, a theorem).
• communication skills: developing and improving the ability to use a suitable language to describe scientific concepts.
• learning skills: ability to use mathematical tools and models in Physics.

## Course Structure

Frontal instruction: theory (7 CFU) and exercise (2 CFU).
