## Learning objectives

At the end of fo the course the students should be able:

- to know the main laws and principles of classical physics and understand their physical sense and main applications.

Being able to use the proper specific language of physics and the related terminology.

- Be able to apply key concepts to specific cases and to understand their potential and their application limits.

- Be able to expose concepts and results even to a general public and to know how to present

to an inexperienced audience the main aspects of the quantitative physical description of phenomena.

- To know how to evaluate the potentialities and limits of a quantitative physical description of phenomena.

- Be able to establish a link between different topics and show judgment autonomy and analytical skills in dealing with specific problems.

## Prerequisites

Students are expected to have a good background of elementary mathematics: and a basic knowledge of the calculus in order to make them able to differentiate and integrate simple functions such as polynomials, sines and cosines.

## Teaching methods

The lessons will be in presence with the possibility of attending the lessons also remotely in synchronous mode (via Teams).

The course is organized in frontal lessons in which topics are discussed and concepts presented. Discussion and interaction with students and the ability to ask questions and ask for clarification is always prioritized and continuously and explicitly encouraged.

The course aims to describe, even quantitatively, a number of significant examples. For these purposes, each final lesson of a certain subject will be immediately followed by a series of exercises during which, always in an interactive way with the students, the applications of the concepts just presented will be discussed.

In addition, each lesson will be introduced by a brief summary of the concepts already discussed in the previous lesson, allowing the single student to have a quick connection with the already presented topics.

Verification tests will be considered as evidence for effective assessment of learning by students. Such checks will also be carried out formally with "class-written tests" (approximately 2 to 3 tests are expected to be planned).

All the didactic material (introductory course material, figures, exercises, math support and trigonometry) is contained in the adopted text. The teacher will publish any additional material on the Elly site.

## Assessment methods and criteria

An active frequency and, as far as possible, continues is highly recommended and allows the student to participate in classroom work, including test opportunities and on-going testing.

Exam methods: the exam methods will be differentiated according to the possibility of taking exams in PRESENCE or (if required

from organizational procedures) REMOTE.

PRESENCE mode: Assessment of learning is done through a written final exam. The student must then, upon enrollment online, take an exam written as announced in the list of the official exam calendar of the Department of Mathematica Physical and Computer Science.

Each written exam of 2 hours will consist of 4 exercises (for each score ranges from 0 to 5) and 10 questions closed (for each the score goes from 0 to 1).

The questions correspond to each part of the chapters chosen from those related to the lessons. The exercises will be similar to those developed during the course.

The student must demonstrate that he has understood, and is able to apply, the fundamental concepts of every topic discussed.

Exam results are published on the Esse3 portal within one week of the examination date. The students can view the exam, after an appointment with the instructor.

In the case of REMOTE mode, the exam will be based on a written test (quiz elly) of 21 questions to be completed within

one hour followed by an oral exam. The partial written test entitles you to participate in all the oral tests of the academic year

in progress.

## Other information

Registration to the course: all students enrolled in the first year of the CD in Informatica in this AA, are required to REGISTER the Physics course before the beginning of the course, as indicated on the campus net site.

They can then receive directly from the teacher in real time all the information and updates related to the course and take advantage of the didactic material provided to them.
