# General Physics I

**Academic Year 2023/2024**- Teacher:

**SALVATORE PLUMARI**

## Expected Learning Outcomes

**Knowledge and ability to understand (knowledge & understanding):** the student will be introduced to the basic knowledge of the laws of classical physics (mechanics, fluids and thermodynamics). The student will develop the ability to understand the most important physical phenomena related to the course program.

**Applying knowledge & understanding:** the student will be initiated to an application in practical fields of acquired knowledge, with continuous examples of applied physics for the understanding of the real world.

**Making judgments:** the student will be induced to a critical analysis of the level of knowledge acquired, pushing him to a self-assessment of his knowledge and skills, trying to develop an autonomy of judgment on the objectives achieved.

**Communication skills: **The interaction with the teacher and colleagues will be stimulated to increase students' communication skills.

**Learning skills:** Ability to learn the scientific concepts of Physics, necessary to undertake subsequent studies with a high degree of autonomy.

## Learning Assessment

### Learning Assessment Procedures

The exam consists of written and oral tests. Admission to the written test is subject to booking on the Student Portal platform. For each session, a precise range of dates is published in which it is possible to book. At the end of the written test, the test is published on STUDIUM, in order to encourage a self-assessment process of the test. The results of the tests will be published on STUDIUM.

- Ongoing tests.There are two ongoing tests of 1 hour each, the first scheduled during the teaching break and the second after the end of the course. The first ongoing test consists of solving 2 problems relating to the topics of the course explained before the teaching break. The second ongoing test consists of solving 2 problems relating to the topics of the course explained after the teaching break. The resolution of each problem is assigned a score between 0 and 7.5. If the overall score obtained in the two ongoing tests is equal to or greater than 18/30, it is possible to take the oral test directly in one of the sessions of first exam session. If the overall score achieved in the two ongoing tests is less than 18/30, it is not recommended to take the oral test. However, being discouraged is not equivalent to a formal ban on taking the oral exam. However, this must be taken in one of the sessions of the first exam sessions for current students.

**- Written tests.** The written test must be
taken in one of the exam sessions provided. Typology: resolution, justified and
clearly commented, of four problems, the level of difficulty is like the
exercises discussed in the classroom. Duration: 120 minutes. Evaluation: from 0
to 7.5 points for each problem solved. The final mark will consider: the
completeness of the description of the Physical and Mathematical Model used for
the solution, the correctness of the mathematical treatment and the correctness
of the result, both from a numerical and dimensional point of view. Each
written test is considered passed if you have achieved a grade of not less than
18/30 with a grade of less than 18/30 you are not advised to take the oral
exam. However, being discouraged from taking the oral exam is not equivalent to
a formal ban on taking the oral exam.

For written tests: i) During the written tests only pen, pencil and calculator are allowed. Books, formulary, mobile phones, discussions between colleagues are not allowed.

**- Oral exam.** The oral exam consists in the
discussion of at least three distinct topics of the program, the first of which
is chosen by the student. During the oral exam, the proof of theorems and
important results included in the program may be required with numerical
evaluations of the order of magnitude of the physical quantities involved in a
given phenomenon.

Final grades will be assigned considering the following criteria:

Rejected: Basic knowledges have not been acquired. The student is not able to solve simple exercises.

18-23: Basic knowledges have been acquired. The student solves simple exercises and has sufficient communications skills and making judgements.

24-27: All the knowledges have been acquired. The student solves all the proposed exercises making few errors and has good communications skills and making judgements.

28-30 cum laude: All the knowledges have been completely acquired. The student applies knowledge and has excellent communications skills, learning skills and making judgements.

Exams may take place online, depending on circumstances.

### Examples of frequently asked questions and / or exercises

The questions asked during the oral exam will be related to the topics of the program. For example:

"State and demonstrate the principle of conservation of mechanical energy"

"Show that a central force is conservative"

"Discuss Newton's laws of dynamics"

"Demonstrate the principle of conservation of momentum"

"Discuss the dynamics of a rigid body: degrees of freedom, equations of motion,

conservation laws"

"Discuss about the thermodynamic equilibrium and the principle of thermal equilibrium"

"Discuss the statements of the second law of thermodynamics and prove their equivalence"
