D1 – Knowledge and understanding. The goal of the course is to provide a robust knowledge of the principles of classical mechanics and of the appropriate mathematical formalism.
D2 – Ability in applying the acquire knowledge Students are expected to be able to solve problems of mechanics.
D3 – Independent thinking. Students are expected to develop a physical intuition and be able to recognize the feature characterizing a physical system or a phenomenon.
D4 – Communication skills. Students are expected to convey the acquired knowledge with a proper terminology.
D5 – Learning skills. Students are expected to be able to read and understand a generic textbook about the introduction to classical mechanics and solve the related exercises
Trigonometry. Fundamentals of differential and integral calculus.
Physical quantities and measurement. Vector calculus. Kinematics of point particles. Dynamics of point particles. Work and Energy. Dynamics of mechanical systems. Dynamics of rigid bodies. Newtonian gravity. Waves and oscillations. Special Relativity.

Lectures and recitations.
Any changes from what is described in this syllabus will be announced promptly via e-mail and Microsoft Teams.
The exam consists of a written test divided into two parts: the first part includes verification questions (open-ended and/or multiple-choice) on the course content, while the second part consists of problems similar to those carried out during the recitations. The multiple-choice questions are evaluated based on the correctness of the provided answers, with points assigned for each correct answer and no penalties for incorrect responses. Each problem and each open-ended question are assessed according to criteria of clarity and correctness on a four-level scale: exemplary, good, sufficient, and insufficient. To pass the exam with a minimum grade of 18/30, a score of at least 60% must be achieved in each section. The total score for questions and problems is above 30 points. To receive the highest grade (30/30 cum laude), a favourable decision from the committee is required. Further details regarding the evaluation criteria and awarding of bonus points will be announced at the beginning of the course.
