## Learning objectives

The course aims at providing a basic understanding of physical processes and laws underlying the properties of matter. Laboratory experiments aim at providing some practical applications of the conceptual instruments highlighted in the class activity.

## Prerequisites

Basic knowledge (high school level) of algebra, trigonometry and differential calculus

## Course unit content

The course aims at providing:

the knowledge and understanding of the main principles of classical physics with focus on mechanics, thermodynamics, electricity and magnetism together with skills in solving simple problems

the methodologies needed to obtain quantitative data from simple experiments and to treat them using error theory.

## Teaching methods

Class lectures

Class exercises coordinated by an instructor, if possible, also laboratory activity carried out in small groups (three-five students)

## Assessment methods and criteria

The exam is divided into:

- An evaluation of the laboratory activity (weight 20%). These evaluations are communicated to the students, at the end of the course, through electronic platform.

- A written test (weight 80%).

- A score of at least 18/30 in the written test is required,in order to pass the exam.

The written test includes: a part of very simple multiple choice exercises, designed to verify the knowledge of the basic concepts; a part of relatively more complex exercises, designed to verify the ability to use and process these basic concepts; a part of general questions that allow the student to present a course topic in complete freedom. The written vote results from an average weighed on the three types of questions.

- Only in exceptional cases, an additional oral examination is possible.

During the tests students can only use a calculator, not connected to the Internet.

The results of the tests will be announced on electronic platform.

Students enrolled in the first year can take part in three partial tests during the course (topics: Mechanics, Thermodynamics, Electromagnetism). An overall average score of not less than 18/30 (with at most one insufficient grade but not less than 15/30) replaces the final written exam.Online registration is always required through the electronic platform.
