Learning objectives

The course aims to provide students with an introduction to the experimental method and the basics of classical mechanics and thermodynamics. Upon completion of the course: students will be able to demonstrate knowledge and understanding of the laws of classical mechanics and thermodynamics; students will be able to apply the acquired knowledge and understanding skills to solve problems of mechanics and thermodynamics; students will have the capability to apply the fundamental concepts of classical mechanics and thermodynamics to the resolution of practical problems that they will meet during forthcoming studies; students will develop the skills required to continue the studies in an autonomous way in those disciplines pertaining to the graduation in Computer Science that require the application and knowledge of the laws of Physics;

Prerequisites and basic notions

Knowledge of mathematical analysis, in particular trigonometry, functions, derivatives and integrals.

Bibliography

Didactic methods

Lectures on the theory, exposition and explanations of the laws, applications with exercises on the blackboard. The lessons are held in the classroom, in presence.

Learning assessment procedures

The exam is written, with a number of exercises to be solved on the course program and similar to those that are done in class. You will be able to use the calculator and notes during the exam. The exam is differentiated between attending and non-attending students.

Evaluation criteria

Knowledge of the basic principles of classical mechanics and thermodynamics, ability to apply the laws in solving complex problems.

Criteria for the composition of the final grade

The vote will be the sum of the scores obtained with the exercises carried out correctly.
