    OVERVIEW

    This course gives all students a common and advanced knowledge base regarding the fundamental concepts of classical physics (mechanics and thermodynamics), paying particular attention to the scientific method used to analyze and solve the problems that arise.

    The course is held in Italian, but questions and discussions can take place also in English and French. Several examples of problems with solutions are provided during the year also in English and French. 

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Aim of this course is to provide a basic knowledge of the principles of classical physics (mechanics, thermodynamics). Study of the fundamentals of kinematics and dynamics of the material point, dynamics of the systems of material points, thermodynamics. Applications of the scientific method to the analysis and resolution of physics problems.

    AIMS AND LEARNING OUTCOMES

    The General Physics course provides a necessary knowledge base for every engineer in the fields of mechanics and thermodynamics. A large fraction of the lessons is dedicated to solving increasingly complex exercises and problems, interchanging theoretical lessons, examples and exercises in the classroom and online. We start from simple and easily schematizable systems, such as material points, and then move on to the mechanical behavior of material point systems, extended bodies and extended body systems. The second part of the course deals with the thermodynamic behavior of solid, liquid and gaseous materials, and with the fundamental principles of the operation of thermal machines (engines) and refrigerators.

    This course enables students to analyze a physical problem, break it down into simple parts, apply the basic principles of physics and calculate the required results.

    PREREQUISITES

    Basic knowledge of algebra and geometry, trigonometry and linear algebra (vectors) are required. It is helpful to be familiar with the concepts of derivatives and integrals. Supplementary exercises at the beginning of the course are planned to fill any gaps in these topics.

    TEACHING METHODS

    Classroom or online theoretical lessons for about 60% of the available time. Examples and exercises for the rest of the hours. Self-assessment exercises at the end of each lesson block (approximately every month).

    EXAMS

    EXAM DESCRIPTION

    The traditional exam takes place in two parts, one written and one oral. The written exam consists of 4 problems, to be solved in 4 hours. Those who obtain a mark of at least 15/30 are admitted to the oral exam. There are 5 sessions available for the written exam (June, July, September, January and February of the following year). The oral exam normally takes place one week after the written exam.

    The complete written exam can be replaced by two partial tests (2 problems in 2 hours) during the year, respectively in January and June, only for students enrolled in the first year. Those who pass both partial tests with a mark of 15/30 are admitted directly to the oral exam.

    The oral exam starts from the discussion of the written exam to ascertain the level of knowledge of each student. The final mark depends on both the written mark and the oral result.

    Traditional written exams can be replaced by online exams consisting of multiple choice quizzes if it is not possible to do otherwise.

    ASSESSMENT METHODS

    The written exam aims to assess the student's ability to face a new problem and solve it on the basis of the knowledge acquired during the course. The oral exam assesses the logical reasoning ability and general knowledge of classical physics.
