Academic Year 2019/2020 - 1° Year

FIS/01 - 9 CFU - 2° Semester

- 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.

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