| Contents | Measurement and units. Kinematics: motion in two and three dimensions. Force and motion. Kinetic energy and work. Potential energy and conservation of energy. Systems of particles. Center of mass and linear mumentum. Collisions. Gravitation. Rotation. Rolling. Torque. Angular momentum and conservation. Equilibrium. Oscillations. |
| Reference texts | Mencuccini, Silvestrini - Fisica I - Liguori Editore Mazzoldi, Nigro, Voci - Fisica - Volume I - EdiSes Feynman, Leighton, Sands - The Feynman lectures on Physics |
| Educational objectives | At the end of the course, it is expected that the students will acquire the basic knowledge of the principles of classic physics. In particular the student will know: - kinematics of the material point; - dynamics of the material point and of systems of material points, including the rigid body; - conservation laws of energy, quantity of motion (linear momentum) and angular momentum. In addition, the student will acquire familiarity with the scientific method and with the techniques for solving problems. The main abilities will be: - to know how to read and to understand the texts of problems and exercises; - to know how to find solutions and to apply the most adequate; - to suggest alternative solutions. |
| Prerequisites | No prerequisite is required. However, in order to be able to effectively follow the lectures, it is useful to be familiar with the basic concepts of Mathematical Analisys. In the first part of the course, if necessary, short reminders to basics necessary to fully understand the specific topic treated, will be given. |
| Teaching methods | Lectures and exercises. |
| Other information | During the course, additional lectures on "how to solve problems" will be given by a tutor. This activity is strongly recommended. |
| Learning verification modality | The exam consists of a written and an oral proof. The written proof is finalized to ascertain the acquired knowledges and the ability to apply them to problem solving; it comprises 4 problems and exercises, on different parts of the program. The student has up to 4 hours at disposal for solving the problems. The admission to the oral proof is subject to a positive judgement of the written proof, namely a score of al least 18/30. The oral proof, of the duration of about 1 hour, aims to ascertain the acquired competence and the understanding capabilities, also from a critical point of view. The final score takes into account the scores of the written and oral proofs. During the course, there will be three written partial tests; in case of positive results, the student can do directly the oral proof. The oral exam can also be taken at a later session. |
