- Contents
- The course is organized into two thematic modules. Part I: Physical quantities and units of measurement. Elements of mechanics: kinematics and dynamics of a material point, work and energy. Part II: Statics and dynamics of fluids. Elements of calorimetry and thermodynamics.
- Reference texts
- The following textbook is adopted: Giancoli, Physics – Principles with Applications. Alternatively: Young, Freedman, Ford, Principles of Physics, Vol. 1, PEARSON; Jewett, Serway, Principles of Physics, Vol. 1, EdiSES.
- Educational objectives
- Provide knowledge of the fundamental principles and laws of physics aimed at understanding natural, productive, and technological processes: physical quantities and units of measurement; basics of vector calculus, kinematics and dynamics of a material point; work and energy; fluids at rest and in motion; calorimetry and thermodynamics. Discuss the implications of these principles in simple problems and practical applications.
- Prerequisites
- Basic concepts of algebra (powers, roots, solutions of first- and second-degree equations, inequalities, systems of equations), geometry (angles, properties of triangles, Cartesian coordinate systems, area and volume of common plane and solid figures), mathematical analysis (elementary functions such as polynomials, trigonometric functions, logarithms, derivatives and their graphical interpretation, integrals of simple functions).
- Teaching methods
- "The course consists of a total of 54 hours of instruction. The teaching method is traditional classroom lecturing, with demonstrations on the board and practical examples. Each lesson is structured to include both an explanatory part and an exercise part, during which questions and problems are proposed and their solution is guided by the professor.
- Other information
- Attendance at lectures and classroom exercises is not mandatory but strongly recommended."
- Learning verification modality
- Assessment is carried out through a written exam. The exam, lasting 120 minutes, consists of 3–4 problems and 2 open-ended questions on theoretical topics.
