We aim to present to the student the main Physics principles dealing with Cinematic, Dynamics, Fluids and Thermodynamic, giving particular evidence to the applicative aspects.
Knowledge and understanding:
The student must demonstrate knowledge and understanding of the fundamentals of classical physics, with particular regard to Cinematics, Dynamics, Fluid dynamics and Thermodynamics, and their application context. The student must know how to use the vectors as physical quantities.
Ability to apply knowledge and understanding:
Students must demonstrate to use their own acquired knowledge to solve the main problems of physics, even when they appear in concrete contexts. These skills have also to be applied to solve exercises.
The student must be able to know how to independently evaluate the results of physical law applications.
The student should be able to support a basic physics conversation by also making examples of application of basic physical laws related to Cinematics, Dynamics, Fluid dynamics and Thermodynamics.
The student must be able to update and deepen autonomously specific topics and applications of physical laws related to Cinematics, Dynamics, Fluid dynamics and Thermodynamics.
The student must know the vectors, operations between vectors and their properties and understand how to use them as physical quantities.
Knowledge of algebra and math analysis is also required.

The purpose of the assessment is to quantify the level of achievement of the training objectives previously indicated. The verification procedure consists of an oral examination during which the ability of the student to apply the physical principles acquired during the course to practical problems is tested.
Lectures are in Italian. The professor is fluent in English and is available to interact with students in English, and to allow the use of English during examinations.
