Module 2
Problem solutions on the arguments of Module 1.
Readings/Bibliography
Several books can be used. Each has specific characteristics that make it valuable, and some critical aspects (in particular, some texts use obsolete notations for some physical quantities). Most of the texts also contain material developed in the courses of Thermal Phenomena and Wave Phenomena.

In English, I suggest (in addition to the American version of Resnik):
 A. Bettini. A Course in Classical Physics 1—Mechanics (Springer)
Finally, a cornerstone of physics (which I recommend to use in second reading).
 La Fisica di Feynman: Zanichelli.English version freely available from the website: https://www.feynmanlectures.caltech.edu/
For other textbooks that you may have available, consult the teacher (some General Physics books for other degree courses are not sufficiently thorough).
Finally, any book with exercises carried out (in the library there are many copies of many editions) and the exercises carried out in all recommended texts are indispensable for Module 2.
Teaching methods
Lectures at the blackboard and solution of problems in the classroom.
Assessment methods
The exam is unique for both modules and it consists of a written proof and an oral assessment. Six written proofs are scheduled in each academic year: three in the first Session (January/February); two in the second (June/July) and one in the third (September). The oral assessments start after the corrections of the writing proofs.
The written test concerns the solution of two distinct exercises. Each exercise is divided into points. As a rule, the difficulty is increasing (the first point is easy, the last is the most difficult). The total time available for the written test is 2 hours. To obtain the maximum score in the written test (31/30), the candidate must solve all the questions. Those requiring numerical solutions must be solved before setting the solution literally. The principles (or laws) applied must be mentioned, and the salient passages must be indicated schematically from the physical point of view. It is recommended to accompany the development with schematic drawings representing the situations. The results must be expressed with an appropriate number of significant digits. Sufficiency (18/30) is achieved by solving completely one of the two proposed exercises, or the initial parts (based on the difficulty) of the two proposed exercises.
A sufficient score in the written proof is a prerequisite for accessing the oral assessment, in one of the defined dates of the Session. The overall length of the oral assessment is about 30 minutes, divided between the teachers responsible for the two modules (the student is examined first by the teacher of one module and then by the teacher of the other). In the oral exam, the accuracy of the answers and definitions, the clarity and synthesis with which the topics are presented and the ability to connect the various topics will be assessed. Each teacher independently evaluate the test with a grade expressed with a maximum score of 31/30. A necessary condition for passing the oral assessment is that the student is evaluated with score >= 18 by both teachers. The verbalized final mark is the average of the three marks obtained (in the written test and in the two parts evaluated by the two oral teachers).
The student has a maximum of 3 days to decide to accept the final grade. After this period, failure to confirm acceptance is equivalent to refusal (which is recorded as such). According to the university teaching regulations, the refusal of the grade is possible at least once by the teacher. In case of refusal, the student will have to start from the written test.
