### Course description

Objectives

Knowledge and Understanding: The students will be able to understand the basic concepts of classical mechanics and thermodynamics. In particular: Newton's laws, work, energy, conservation of energy, the principles of thermodynamics.

Applying Knowledge and Understanding: The student will be able to understand

the proposed problems during the course and the ability to properly apply theoretical knowledge. The student will be able to proceed to the qualitative and quantitative study of the physical processes of classical mechanics and thermodynamics, to solve kinematic problems and classical dynamics for a material point, material point systems and rigid bodies. The student will also be able to solve simple thermodynamic problems.

Autonomy in Judgement: The student must be able to deepen his / her own knowledge as he / she learns and therefore, he / she must develop the ability to critically evaluate the problems and propose the most appropriate approach to solve them. The student will be able to recognize a physical phenomenon and the laws which govern it, to understand the most relevant physical quantities involved and to give an estimate of them.

Communication Skills: The student must have the ability to expose and communicate his / her knowledge with appropriate scientific language. In addition, the student must demonstrate logical-deductive and synthesis skills in the communication.

Learning Skills: The acquired knowledge will allow the student to further study the classical physics and to apply the methodologies of physical sciences to other subjects. The student will be able to integrate knowledge from various sources in order to gain a broad view of the issues related to the topics and to develop the necessary connections between concrete examples and the knowledge of physics acquired in the course.

This course is entirely taught in Italian. Study materials can be provided in the English and the final exam can be taken in English.

### Teaching Methods

Educational approach forming: frontal lessons and practical classes.

Lectures and exercise classes will be characterized by strong interactivity

during which active participation of the students is required.

### Textbooks

Mencuccini, Silvestrini Fisica Generale I (ed. Liguori)

Mazzoldi, Nigro, Voci Fisica Generale I (ed. EdiSes)

More informations can be found on the website edi.uniparthenope.it (A password is required).

### Learning assessment

The exam is composed by a written exam (problems to be solved) and an oral exam.

The written exam consists of exercises on different subjects of the course. The oral exam can be taken only if the written exam is passed.
