Subject: PHYSICS (A.A. 2021/2022)
The course aims to extend student’s knowledge to fundamental aspects of Nature phenomena related to classical mechanics and electromagnetism and the laws of physics behind them. Furthermore some basic features of the modern atomic model and their impact on the phycical properties of molecules and solids will be discussed. Students will also learn the use of math as instrument of quantitative understanding of physical phenomena.
Students are encouraged to attend Basic courses of vector algebra and differential and integral calculus.
The course encompasses 48 lectures (6 CFU) (attendance is not mandatory, but strongly recommended) together with 20 hours of tutorial activities, mainly focused on the analytical solution of problems.
List f the main topics dealt with:
1. Physical quantities. Vectors. Mechanics. Kinematic of point. Forces and Newton‘s laws of motion. Circular motion. Work and Energy. Matter waves.
2. Electricity and Magnetism. Electrostatics. Electric Field. Gauss Law. Electric potential. Capacitance and dielectrics. Current and electrical resistance. DC circuits. Magnetic fields. Faraday’s law. Inductance. Electromagnetic waves. Elements of optics.
3. Elements of modern physics. Rutherford atomistic model. Bohr’s model. Energy levels for bound systems of atoms: molecules and solids.
The course will be held in italian. It includes classroom lectures, analytical solutions of problems, real experiments shown through movies. The support material made available by the teacher for a year from the last day of the class will be loaded on the Moodle "Dolly" platform. Students must subscribe to the course in order to access to the published material. News about the course will be sent by the teacher from the same platform to the student's registered email box.
9 sessions fo oral examination to be held in presence or with remote connection (through Moodle Collaborate or Google Meet). The Exam Committee Members are: R. Brunetti, C. Jacoboni, and B. Morten. The oral examination, lasting from about 30 to 45 minutes, includes the mandatory solution of an exercise chosen from a collection of exercises with solution published on Dolly of the present Academic Year. If the exercise is correctly solved, the exam will preceed with tho questions on topics included into the Syllabys published on Dolly of the present Academic Year. Each of the three sections contributes to 1/3 of the final exam mark.At the end of the exam students will know their mark (x/30) and they will be allowed to reject the mark within the same day until midnight. If the teaching activities will be planned in presence, two written tests, focused on classical mechanics (first test) and electromagnetism and modern physics (second test), respectively, will be proposed during the semester with three multiple-choice (maximum points: 4 each) and three open-answer questions (maximum points: 6 each). If both tests are passed the exam can be registered without any other assessment. Whatever choice for the exam by the student, the numerical analysis of a case study will test the student's attitute to apply math concepts to implement theoretical aspects and obtain a quantitative description of the physical phenomena. The remaining part of the exam will access the student's understanding of the fundamental concepts and laws of classical physics to describe macroscopic phenomena.
Knowledge and comprehension: students get the main concepts of classic (mechanics, electromagnetism) and modern Physics through class lectures.
Application of the concepts to real problems: the application of physics concepts to real problems is demonstrated through examples during lectures.
Independent analysis: through the lecture students become able to formulate questions about Physical theories and to discuss the answers.
Communication abilities: the acquisition of a proper terminology make students able to express and discuss Physics problems.
Learning ability: concepts and methodologies acquired during the course help the student to proceed in his study on a sound basis and keep their knowledge updated.
