5. Special relativity (SR). Accelerating and inertial frames. Galilean transformations. Lorentz transformations. Linear momentum and energy in SR. Nuclear energy.

- Demonstration of the syllabus coherence with the curricular unit's objectives
The syllabus follows the criteria used internationally in similar courses in engineering degrees. Lectures always include several practical examples which promote classroom discussion and easier assimilation of the theory as well as its connection to other courses in the LEB. The exercises proposed in the problem sets (more than 200) allow students, individually or in group, to apply the theoretical concepts to a wide variety of practical situations and thus gain the necessary confidence and skills to use them correctly in many different contexts. This is to impart to students that calculation is an essential ingredient of physics and the ability to obtain numerical results that can be checked by experimental observation underpins the huge success of modern sciences and technologies.

- Teaching methodologies
The lectures follow the expository method, always accompanied by practical examples and with extensive use of the white board. Problems classes are designed to clarify difficulties encounterd when solving the problem sets that are expected to have been previously worked out by the students. The course Moodle pages contain extensive study material, past exams and external links to complementary study material, including videos and virtual experiments (Java applets).

Assessment:

Assessment for this course is in the form of one written test, taken at the end of semester, and/or a written exam, taken on either of two set dates. Both test and exam are of 2.5 hours duration and cover the entire syllabus.

The minimum pass grade is 10 (out of a maximum of 20) in all cases.

- Demonstration of the coherence between the teaching methodologies and the learning outcomes
Solving a large number of exercises allows students to strengthen their theoretical knowledge through hands-on practice. Real life examples are used to make a connection with the real world and with other courses The aim is also to enhance student participation and motivation.
