B1869 - FISICA (8 CFU) (M-Z)

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

Teaching methods

The course is formed by two 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. Module 2 has  an experimental character and consists of laboratory activities (1 CFU). The three experiences concern mechanics, optics and thermodynamics, respectively.

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 of Module 2, providing all the relative relations (3 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 activities of Module 2.

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.

Teaching tools

Blackboard, video projector, online broadcas, slides containing theory and exercises

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