Learning objectives
The course is proposed to provide the fundamental knowledge of physics, required and correlated to other teachings foreseen by the Course of Degree.
Expected learning outcomes
Knowledge of the principal physical quantities (i.e. those that are often used during the Course of Degree), their dimensions and units of measurement. The student must be able to recognize and to resolve formally and/or numerically simple problems of physics, related to the technological practices and/or the research in the frame of food technology.
