- Contents
- The course covers the fundamentals of classical physics, starting with physical quantities and units of measurement, followed by vector calculus and kinematics. It explores Newton's laws of dynamics, the concepts of force, work, and energy. The course also includes fluid mechanics, with an introduction to hydrostatics and fluid dynamics, as well as topics in calorimetry, ideal gases, and the principles of thermodynamics. It concludes with a brief overview of error theory.

- Provide students with a solid understanding of the fundamental principles and laws of physics, aimed at interpreting and analyzing natural phenomena, production processes, and technologies. The course covers key topics such as physical quantities and units of measurement, an introduction to vector calculus, kinematics and dynamics of a material point, work and energy, the behavior of fluids in static and dynamic conditions, calorimetry, and thermodynamics. The course also aims to develop the ability to apply this knowledge to solve basic problems and in practical contexts.
- Prerequisites
- Basic knowledge 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), and mathematical analysis (elementary functions such as polynomials, trigonometric functions, logarithms, derivatives and their graphical interpretation, integrals of simple functions).
- Teaching methods
- The course has a total duration of 54 hours, divided into sessions of 2 or 3 hours each. Teaching is primarily delivered through lectures, supported by slide presentations, along with demonstrations and problem-solving on the board. Each lesson is structured in two parts: the first focused on the theoretical explanation of concepts, and the second dedicated to practical application, during which exercises and problems are presented and solved with the guidance of the professor.
- Other information
- Attendance at lectures and classroom exercises is not mandatory, but it is strongly recommended for a better understanding of the course content.
- Learning verification modality
- The course is assessed through a written exam lasting 2 hours, consisting of 11 theoretical questions and problems.
