This course unit provides students with a framework for applying the concepts and techniques learned throughout its course, while granting him a background in the field of mechanics. This background will enable the student to better understand the world, its constituent parts and interactions between them.

Wave Mecanics

1.Using suitably the physics-mathematical language to structure and express opinions.
2.Applying physic concepts, principles and theories to problematic situations of the real world.
3.Searching, selecting and organising information to later turn into applicable knowledge to daily phenomena.
4.Adopting scientific strategies suitable for problem solving and decision making.
5.Performing activities in an autonomous, responsible and creative way, in a collaborative environment.

E-learning (fully online).

Continuous assessment is privileged: 2 or 3 digital written documents (e-folios) during the semester (40%) and a presence-based final exam (p-folio) in the end of the semester (60%). In due time, students can alternatively choose to perform one final presence-based exam (100%).

Course unit pre-requisites:
• knowledge of vector, differential and integral calculus and linear algebra.
