66676 - General Physics

Learning outcomes

At the end of the course, the student will know of the notion of measurement in classical physics and the methods of presenting experimental results. They will have learnt the fundamentals of classical thermodynamics and of electric and magnetic phenomena. They will know how to use the acquired knowledge to solve simple problems connected with the kinetic theory of gases, with the creation of electric and magnetic fields, and with the wave aspects of oscillating electromagnetic fields. In particular, they will learn how to analyse information relating to the different phenomenologies of thermodynamics and electromagnetic phenomena.

Course contents

MODULE 1: Electromagnetism (Prof. Pedro, 40 h)

The module aims to give an introduction to electric and magnetic phenomena and to the theory of electromagnetism.

Assessment methods

The vote for the course is unique and can be recorded only after the tests of both modules have been successfully passed.
The final mark is obtained by taking the arithmetic mean of the two marks for the module 1 and 2, rounded up. Any cum laude in the two modules does not enter into the calculation of the average and the cum laude in the final mark is attributed only if obtained in both modules.
The exams of the two modules are independent and can be taken in any order. The vote of each of the two parts remains valid also for the three subsequent exam sessions.
For the timetable of the exams, refer to AlmaEsami, where registration is compulsory for both the written and oral exams, within two days before the date of the exam session.

Tests for each modules:

• Written test (mandatory)

It includes both theory topics and exercises.
It consists of 20 multiple choice questions, worth 1 point for each correct answer, and 2 multiple choice questions, worth 2 points for each correct answer, for a maximum total of 24 points.
The test is passed if a minimum score of 10 points is reached, which will correspond to a grade of 18/30. Each additional point corresponds to one more vote. A score of 31/30 or 32/30 is equivalent to honors. (Examples: 10 points = 18/30; 20 points = 28/30; 22 points = 30/30; 23 or 24 points = 30/30 with L)
If the student passes the written exam, they can:
- Refuse the grade (with an e-mail to the teacher).
Please note that, in accordance with the University Regulations, it is possible to refuse the mark (for each of the two tests) only once. However, it is possible to withdraw at any time during the exam, both during the written exam and during the oral exam.
or
- Accept the grade (default choice), which will then be recorded if both modules have been passed.
or
- Register for the oral exam (with an e-mail to the teacher), allowed only if the grade of the written test is equal to or higher than 26.

• Oral test (optional)

It must be taken in the same appeal.
- It can be taken only if the grade of the written exam is equal to or higher than 26.
- The final grade can increase by a maximum of two points.

Teaching tools

For both modules, handouts with the contents of the course and the exercises carried out in class are available on Virtuale.
