Learning Objectives
The course is intended to teach a scientific method for the analysis of main physics phenomena
on the following themes: mechanics, thermodynamic.
Prerequisites
1) Nozioni di matematica secondo quanto previsto dai programmi ministeriali della scuola secondaria superiore.
2) Capacità di utilizzare correttamente tali nozioni e di eseguire le operazioni ed i calcoli relativi. 1) Knowledge of High School Maths concepts,
2) ability to correctly use such concepts in calculus.
Teaching Methods
Lessons and assignments with solutions.
Type of Assessment
written and oral exams for both Physics I: mechanics and thermodynamics and Physics II: electromagnetism and introduction to modern physics. Oral exam is not compulsory if the score of the relative written exam is equal or higher than 21/30.
