Students are free to use any other text that may be more convenient for them.

The teaching material is mainly represented by the notes taken during the lessons and exercises, enriched by the discussions triggered by the teacher in the classroom. Furthermore, the reference texts represent a fundamental tool for the student also in order to acquire the necessary autonomy in the study of the discipline. Any slides of the helded lectures will be published on Studium.

The examination consists of two compulsory components: a written examination and an oral examination.

WRITTEN EXAMINATION

The written examination is designed to assess students’ theoretical and practical skills, as well as their ability to solve basic problems by applying fundamental laws of physics. It consists of four problems covering the following topics:

• Vector calculus and kinematics;

• Particle dynamics and system dynamics;

• Fluid dynamics;

• Thermodynamics.

Each problem is graded on a scale ranging from 0/30 to 7.5/30. The assessment takes into account (1) the completeness of the description of the physical and mathematical models used to solve the problem, (2) the correctness of the mathematical procedures, and (3) the accuracy of the final result, both numerically and dimensionally.

Students who obtain a minimum grade of 18/30 in the written examination are eligible to take the oral examination. Students who obtain a grade below 18/30 are advised not to proceed to the oral examination. For students who obtain a grade equal to or higher than 15/30 but below 18/30, admission to the oral examination is subject to a preliminary assessment of their basic knowledge.

ORAL EXAMINATION

Students who pass the written examination must take the oral examination on the date scheduled within the same examination session. In the event of specific needs or circumstances, students should contact the lecturer using their institutional email address.

The oral examination consists of an interview covering the topics addressed during the course. Its purpose is to assess students’ knowledge and understanding of the course content, as well as their ability to explain and apply the laws of physics.

The oral examination is assessed according to the following criteria: knowledge and understanding of the topics covered, clarity of expression and appropriate use of scientific terminology, ability to apply knowledge to simple problems and case studies, and ability to establish connections between the different topics included in the course syllabus.

Students who fail the oral examination MUST retake the written examination.

The final examination grade is based on the results of both components, weighted as follows: written examination: 40% of the final grade; oral examination: 60% of the final grade.

IMPORTANT: Passing the oral examination is a necessary condition for passing the overall examination. Failure to attend the oral examination or inability to answer the questions (resulting in a score of zero) will result in failure of the entire examination, regardless of the grade obtained in the written examination.

During the written examination, the use of formula sheets and any electronic devices is prohibited, with the sole exception of a calculator that is not connected to the Internet.

Registration for each examination session is mandatory and must be completed exclusively online, through the Student Portal, within the designated registration period.

The assessment of learning outcomes may also be conducted remotely if circumstances require it.

USE OF ARTIFICIAL INTELLIGENCE TOOLS

In accordance with the University's Guidelines on the Use of Artificial Intelligence Systems, the use of such tools is prohibited during examinations, in-course tests, and any other assessment activities.

Any violation of this prohibition may constitute a breach of the obligations established by the University Statute, the Code of Ethics and Conduct, and University Regulations, and may result in the initiation of the disciplinary procedures provided for therein.

With regard to the written examination, the lecturer also reserves the right to invite students to an individual interview in order to verify the authenticity and integrity of their submitted work.
