Training objectives
- The course aims to provide the basic elements of Classical Physics, the methods for the description of physical laws.
The main objective is to provide students with the ability to apply the principles of kinematics and dynamics, fluidostatics and fluid dynamics, thermodynamics to simple systems.
Another purpose is to acquire skills in applying the laws of electromagnetism, in identifying the properties of electromagnetic waves and in applying the laws of geometric optics.
The lessons and guided exercises will allow you to acquire the skills required to set up the resolution of simple problems in this area in a scientific and quantitative way. Prerequisites
- It is necessary to have acquired and assimilated the following knowledge provided by the course of Elements of Mathematics and Statistics:
- literal calculation, of the fundamental numerical sets and their properties;
- first and second degree equations, inequalities and systems of equations;
- Cartesian plane and graphical representation of the functions;
- main trigonometric functions;
- concept of limit, derivative and integral of a function. Course programme

- - The Physics course includes 48 hours of lessons in the classroom on all the topics of the course.
- There will be exercises, both during the lessons with the teachers and with the didactic tutor. Learning assessment procedures
- The objective of the exam is to verify the level of achievement of the previously indicated training objectives.
There is a written exam consisting of multiple choice questions (of which only one is exact) on a computer platform, or OMR cards, on topics related to the entire program carried out in class.
The use of the calculator and a form provided by the teachers is allowed. Reference texts
