Learning outcomes

After completing this course, the student masters the conceptual and methodological tools of physics, which are required to successfully follow the courses in chemistry and biology. In particular, he/she will acquire a basic knowledge of classical physics (Kinematics, Dynamics, Thermodynamics, Electricity, Magnetism, Waves), and the ability to solve simple exercises related to the subjects handled, as well as to acquire experimental data in laboratory experiences and elaborate the results obtained.

    Teaching methods

    The course is formed by three didactic units. Module 1 (7 CFU) consists of theoretical lectures, accompanied by the discussion and resolution of several exercises, to reinforce the learning of general principles. Modules 2 and 3 have an experimental character and consists of laboratory (1 CFU) and data analysis (1 CFU) activities. The three experiences concern mechanics, optics and thermodynamics, respectively.

    As concerns the teaching methods of this course unit, all students must attend Module 1, 2 online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme.

    Assessment methods

    The assessment consists in a written examination and an oral interview.

    The written test, lasting 2 hours, consists of solving 6 problems concerning the topics of the course program. The use of calculators is allowed. Each problem will be rated from 0 to 5 points (0 if unsolved or totally wrong; from 1 to 4 points if partially solved; 5 points if correct). The validity of the written exam extends only over the academic year during which the written exam has been passed.

    To take the oral interview, it is required to have passed the written exam, and to have attended all the experiments and data analysis experiences of Modules 2 and 3, providing all the relative relations (6 in total). The oral interview, lasting about 20 minutes, aims to assess the knowledge of the topics covered in the program, including demonstrations, and the student's exhibition quality. Moreover, the oral interview includes questions about the laboratory and data analysis activities of Module 2 and 3. A successful oral interview can increase the score of the written examination, up to a maximum of 20%. Conversely, if the oral interview is evaluated negatively, it might determine a reduction of the score of the written examination, up to a maximum of 20%.

    If the grade is lower than 18, or the student decides not to accept it, the exam (written+oral) can be taken in any of the following sessions, without restrictions. "Lode" will be considered only in exceptional cases, after passing both the written examination and the oral interview with top scores.

    The Professor who will verbalize the exam is the responsible of Module 1. To get the exam verbalized, it is sufficient for the student to communicate to the Professor that he/she accepts the proposed evaluations.

    Teaching tools

    The slides of the lessons of Module 1, and all teaching materials of the laboratories and data analysis of Modules 2 and 3 are provided during the course at the web page Virtuale.
