Reference texts
The following textbooks are advised, alternatively:
- Young, Freedman, Ford, Principi di Fisica, Vol. 1, PEARSON;
Educational objectives
The student is expected to acquire the basic knowledge about the physical laws that are fundamental for the comprehension of natural, productive and technological processes: physical quantities and units, vector calculations, kinematics and dynamics of the material point, work and energy, statics and dynamics of fluids, calorimetry, thermodynamics. The student is also expected to apply such knowledge in the solution of simple problems and practical applications.
Prerequisites
Basic notions of algebra (power, roots, solution of first and second order equations), geometry (angles, properties of triangles, Cartesian systems, area and volume of common plane and solid figures), analysis (elementary functions like polynomial, trigonometric, exponential and logarithmic functions, derivatives and graphical interpretation, integrals of simple functions).
Teaching methods
The course is essentially divided into 4 topics (in addition to the introductory part): kinematics and dynamics of the material point, work and energy, fluid mechanics, thermodynamics and calorimetry. Each topic will be addressed through lectures during which the theoretical bases of each topic will be presented, accompanied by examples and exercises. There will be optional activities in classroom and at home that will increase, if carried out properly, the final vote.
Other information
Attending the lectures and exercise classes is not mandatory, but advised.
Learning verification modality
The exam includes a written test and an optional oral exam.
Each test lasts 90 minutes and consists of multiple choice questions.
The oral exam is optional and will consist of a discussion of about 20 minutes aimed at verifying the level of knowledge of the theoretical topics, the ability to communicate them using an appropriate language.
