OVERVIEW

The Physics course includes theoretical lessons and an important part of exercises done in the classroom. The study is aimed at providing the basis to more efficiently deal with the continuation of the studies. The problems of classical physics will be addressed with the resolution of elementary problems.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to deepen the knowledge of classical physics and provide a scientific method to solve simple problems. The course provides a summary of mechanics focusing on  topics at are a necessary support for other classes, the study of thermodynamics (I and II principle, thermodynamic potentials) and of ideal and real fluids (hydrostatic, surface tension, viscosity, turbulence), therefore elements of electricity and magnetism (notions of electrostatics, charge and discharge of a capacitor, magnetic effects of currents). Finally, introduction to the basic principles of electromagnetic and corpuscular radiation, with particular attention to geometric optics and the study of lenses.

AIMS AND LEARNING OUTCOMES

The course aims to provide the student with the essential tools for the study of the fundamental phenomena of Physics, from mechanics to thermodynamics to electromagnetism. In particular, it intended to provide during the course a methodology that allows the student to deal with new topics gradually encountered in subsequent studies.

TEACHING METHODS

The course includes theoretical lectures and resolution of exercises. Basic knowledge of mathematics is important and frequency is strongly recommended. During the year, exam simulation tests will be carried out proposing to the students exercises on the different parts of the program.

EXAM DESCRIPTION

The exam takes place through a mandatory written test for all students. The written test is followed by an oral exam, optional for students who have obtained a sufficient evaluation of the written test (≥ 18/30), mandatory for students with a score <18.
120 minutes will be available to complete the test, textbooks and notes can be consulted. After the correction, the documents are discussed with the interested students. The oral exam takes place in the presence of two tenured teachers, and it lasts approximately 30 minutes on average.
The deadline for registration is five days before the date of the exam. Exceptions to this deadline will not be admitted.
If the score of the written test will be <13, the student will have to reapply to a subsequent session, but not before 28 days.

ASSESSMENT METHODS

The assessment of learning is verified in a the written exam. When necessary and / or required, an oral exam is provided to deepen the knowledge and the ability to link the topics studied.
