#### Learning outcomes

This course aims at giving the basic knowledge of the concepts of mechanics, thermodynamics electromagnetism and optical to students and the capacity of using the laws of these phenomena in a predictive way. The aim of the course is also to furnish the fundamentals of the experimental method and the concepts by which students can autonomously attack problems involving such phenomena. The course comprises mathematical numerical exercises to allowing students to successfully operate in the final exam.
