Learning Objectives

The course aims at providing basic knowlegde of classical mechanics and thermodynamics topics included in the "Course Content" (see below) as well as the capability to apply the Scientific Method to the resolution of real and concrete problems. In particular, the course has the objectives to provide the bachelor students with the following knowledge and abilities.


- Knowledge and understanding abilities
Knowledge of the main phenomenological aspects related to classical mechanics and thermodynamics and understanding of their physical implications and their mathematical description.


- Applying knowledge and understanding ability
Ability to recognize the main physical laws that govern a mechanic or thermodynamic phenomenon, and to apply them to solve problems and exercises at different levels of complexity and therefore of approximation, with the use of appropriate analytical and numerical techniques.

- Ability of making judgements

- Communication skills
Capability to expose scientific concepts in a proper and inambiguous manner.

- Learning skills
Application to Physics of theoretical/mathematical techniques.


Course Structure

Prerequisites

 

Planned learning activities and teaching methods

 

Attendance to lectures

Although it is not mandatory, attendance to classroom lectures is recommended.

 

 

Learning verification

The final exam consists of a written test followed by an oral exam. Ongoing tests (so-called "prove in itinere") are not planned.
