 At the end of the course the student should have acquired (descriptor Dublin 1) the main basic knowledge of the mechanics of the point, of particle systems and rigid body, and have assimilated the fundamentals of universal gravitation. The student must have a thorough knowledge of the principles of conservation in physics, the force fields and their specific properties and the elementary models for the treatment of complex mechanical systems.
Students will also be provided with the basis for understanding the fundamental principles of electromagnetism and Maxwell's equations starting from the observation of the natural electromagnetic phenomena.
The main skills acquired (ability to apply their knowledge, descriptor Dublin 2, and to adopt the appropriate approach under independent judgment, Dublin descriptor 3) will consist of the ability to model physical phenomena, together with the skills to solve exercises and problems and the ability to individually develop simple demonstrations based on the extension and application of the knowledge acquired.  Prerequisites
 To successfully address the study of the Physics Course and to more easily understand the topics covered, a solid knowledge of basic mathematics ( equations of various degrees , inequalities , systems of equations), trigonometry , elementary geometry and analytical geometry (study of functions, etc.) is mandatory. It is also required the knowledge of vectors and vector operations. For a deeper understanding of the initial topics of kinematics covered in the course, the knowledge of the basic techniques of differentiation and integration is useful. This knowledge becomes mandatory with progressing of the course even though the parallel treatment of these topics in the course Analysis I should help the student. Knowledge of all the mathematical techniques listed and the ability to apply them effectively to solve problems are prerequisites essential to follow the course with profit.
 Teaching methods
 The course is organized in facetoface lectures. There are 96 hours of lectures (72 for the Physics I and 24 for Physics II). Each lesson is typically a 30minute explanation and 15 minutes of training with solution of problems and questions and discussion of applications. At the end of each cycle of thematically consistent lessons there are scheduled classroom exercises conducted by the teacher and consisting in solving problems. The hours dedicated to tutorials and practical training are in addition to those dedicated to lectures. The students are also offered to participate to four written tests with open answers for evaluation and selfassessment.
 Other information
 Optional but strongly advised.
 Learning verification modality
 The assessment of the level of student knowledge and ability achieved by the student is carried out consistently throughout the course. In fact, students are given "in progress" written tests at the end of major specific blocks of lectures thematically consistent. The purpose is in progress verification of the level of knowledge achieved by the student on the subjects of the specific block, offering, at the same time, the student a tool for selfassessment with respect to her/his level of understanding and her/his ability to solve problems. The student can apply to all written tests, regardless of the result achieved in each, or any number she/he wishes to. Each in progress test, although limited as to the specific content of the thematic block, simulates the structure of the written exam and contains problems with open answer questions to be solved in no more than 30 minutes each. Students who have obtained a positive assessment (> 18/30) in more than half of the in progress tests may, if they wish, be exempted from carrying out the final written exam.
The learning assessment (exam) involves passing a mandatory written test, which requires solving problems with open answer questions and the written description of topics selected from the entire course and also including simple theoretical demonstrations. The student who, as a result of the inprogress evaluation has been exempted from the final written test, can apply to it again if she/he so wishes.
The exam tests are designed to ensure: i) the ability to understand the problems proposed during the course, ii) the ability to correctly apply the theoretical knowledge (descriptor Dublin 2), iii) the ability to independently express judgment and appropriate comments on possible alternative models (descriptor Dublin 3), iv) the ability to communicate effectively in writing (descriptor Dublin 4).
