Subject fundamentals
The main objective of the Physics I course is to provide the students with a solid scientific base, aimed to mature understanding and quantitative description of the fundamental laws of nature, concerning mechanics, electrostatics and thermodynamics.
Expected learning outcomes
- Knowledge and understanding (acquisition of theoretical and experimental skills in mechanics, fundamentals of electrostatics and thermodynamics and critical understanding of their laws; start understanding the scientific method, the nature and modalities of research in Physics).
- Practical application of the acquired knowledge (ability to identify the essential elements of a phenomenon, in terms of magnitude order and required level of approximation; ability to apply laws and theorems to practical situations through problem solving).
Prerequisites / Assumed knowledge

Assessment and grading criteria
The goal of the exam is to test the knowledge of the candidate about the topics included in the official program of Physics I and to verify the skill in solving problems. The exam consists of two steps: a written exam followed by an obligatory oral exam. The assessment of both the written and the oral part is based on marks ranging from 0 to 30 (the maximum is 30 out of 30 cum laude).
The final assessment is determined by considering both the marks obtained in the written exam and the interview.

WRITTEN EXAM: a mark less than 16 out of 30 in the written exam is not sufficient for the admission to the oral exam.
Candidates are not allowed to take in the exam room text-books or notes relevant to the Physics-I program. The use of electronic calculators can be allowed provided these are cleared of all pre-stored programmes or information.
The written exam consists of 3-4 questions. In general, these are exercises with the same degree of difficulty of the exercises discussed in the Physics-I lectures devoted to applications (esercitazioni). Part of these questions, however, might be focused on the theory included in the Physics-I program. One of the extended questions can be substituted by a test with multiple-choice short questions.
The exercises proposed in this exam are inspired by the exercises/examples contained in the textbook used by the course lecturer. The text-book will be indicated by the lecturer at the beginning of the course.

ORAL EXAM: students are admitted to the oral exam if the assessment of their written exam is 16 marks out of 30 or more. The assessment of oral exam cannot be less than 18 marks out of 30.
The exam is passed if the final assessment (accounting for the marks of the written and oral exam) is 18 marks out of 30 or more.
Oral exam is mainly oriented to check whether a candidate has a sufficiently wide knowledge of the theory of the Physics-I program. Oral exam may include questions concerning the written exam of the candidate and his activity in the physics laboratory. The theoretical topics discussed in the course lectures are summarized in the program of Physics-I courses of the Politecnico.
In general, the oral exam must be passed in the same exam session (appello) in which the written exam is passed.
