Learning objectives
At the end of 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.

Teaching methods
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.
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.
Assessment of learning is done through a written final exam and an oral 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 SCVSA.
The written test, lasting one hour, 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
They can view the exam, after appointment with the teacher.
If necessary, the written test will take place online (via Teams and Elly), the oral test on the Teams platform.
