Course description

We aim to present to the student the main Physics principles dealing with Cinematic, Dynamics, Fluids and Thermodynamic, giving 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 application contexts. These skills have also to be applied to solve exercises.

Independent judgment:
The student must be able to know how to independently evaluate the results of physical law applications.

Communication Skills:
The student should be able to support a basic physics conversation by also making examples of application of basic physical laws

Learning Skills:
The student must be able to update and deepen autonomously specific topics and applications of physical laws.

Prerequisites

The student must have good knowledge of basic mathematics and analysis (functions, derivatives, integrals)

Teaching Methods

Lectures with the support of the blackboard and of projected slides.
Exercises will be proposed to be solved in team.

Textbooks

Fundamentals of Physics, Vol. I
J. Walker, D. Halliday, R. R. Resnick
Wiley
Other textbooks may be used; it is recommended to check with professors; e.g.,
Mencuccini, Silvestrini Fisica Generale I (ed. Liguori)
Mazzoldi, Nigro, Voci Fisica Generale I (ed. EdiSes)

Learning assessment

The purpose of the assessment is to quantify the level of achievement of the training objectives previously indicated. The verification procedure consists of a written examination (exercises to be solved) and an oral examination, which follows a positive written examination.

More information

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.
