Learning outcomes

This course is designed for students of the Master degree in Computer Science. The course will be focussed on the foundations of the experimental method, the classical mechanics of a particle and systems of particles and thermodynamics.
The educational objectives will be reached through lessons and exercises; lessons will be held during the second semester for a total of 6 credits. To facilitate the student in understanding and learning the laws and principles of mechanics and thermodynamics, during the lectures, frequent recall to phenomenology will be performed. The course is completed by exercises in order to prepare students for final exams .

Assessment methods and criteria

The final exam will be in written and will be focussed on solving typical problems of general physics (mechanics and thermodynamics) followed by an optional oral test. Necessary condition for passing the exam is to obtain a minimum mark of 18/30 in the written test. The oral test will be performed only for those students that have had in the written test a minimum mark of 26/30.
The dates of the exams are decided in harmony with the academic calendar approved by the Faculty.
