Prerequisites
Due to the fact that it is a first-year subject, there are no specific indispensable requirements to take the subject.
It is highly recommended, however, that students who did not take physics during secondary education review the course materials that the faculty makes available to them before the course starts.
It is essential not to make mistakes with units. There are failures that can be avoided simply by avoiding these errors.
Objectives
The Physics subject is one of the basic and compulsory training subjects. The main purpose of this subject, as well as all those that make up the basic training block, is to provide the basic analytical and methodological knowledge and tools to develop transversal skills in the area of environmental science studies. In particular, the subject must help students understand the fundamental laws of physics that govern the natural environment.
In addition, it contributes to the professional training of students as it encourages learning in a series of general skills (among which stand out the ability to reason critically and to improve independent work strategies), transversal (such as know how to discriminate between the key elements of a given problem and be able to size it correctly) and specific (distinguish the biophysical aspects of human activity) which will be of great use to future professionals in the evaluation and management of all types of problems related to the environment, the use of natural resources and energy generation.

Learning activities and methodology
| Title | Hours | ECTS | Learning outcomes |
|---|---|---|---|
| Practice tutorial | 5 | 0.2 | |
| Exercises classes | 12 | 0.48 | |
| Theory classes | 37 | 1.48 | |
| Seminars | 1 | 0.04 | |
| Personal study | 76 | 3.04 |
The body of the subject is made up of theoretical and problem classes, and a seminar session, where the theoretical and practical contents of the course are explained. The rest of the training consists of the student's personal work.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Seminars | 15 | 15 | 0.6 | CM13, CM14, KM20, KM21, KM22, KM23, SM19, SM20, SM21 |
| Partial exams | 85 | 4 | 0.16 | CM13, CM14, KM20, KM21, KM22, KM23, SM19, SM20, SM21 |
85% of the final grade is calculated based on the grades of two partial exams. These will consist of theoretical and practical questions with test questions, and practical problems.
The remaining 15% of the final mark corresponds to the grade for the deliveries related to the seminars.
RESIT EXAM
To pass the subject, two conditions must be met:
- the grade for each partial exam must be equal to or greater than 3.5 out of 10
- the overall grade for the course must be equal to or greater than 5 out of 10
If any of these conditions are not met, there is a resit exam for each part. The resit exams consist of a test section and the resolution of practical problems, and count for 85% of the overall grade. The grade for the assignments is not recoverable.
To pass the subject you must obtain an overall grade for the course greater than or equal to 5. If this condition is not reached, there is a resit exam where the entire course syllabus is included. This exam consists of a part of test questions and the resolution of practical problems, and it counts for 85% of the overall grade. The deliveries mark cannot be recovered.
In accordance with university regulations, to be able to attend the recovery, students must have been previously evaluated in activities that are equivalent to at least 2/3 of all the evaluable activities of the course.
Unassessable: The grade of Unassessable will be obtained if the student does not take any exam.
SINGLE EVALUATION
Students who have accepted the single evaluation modality must take a final test that will consist of a written exam that will consist of the resolution of theoretical-practical questions and problems. This test will be taken on the same day as the second exam of the continuous evaluation. When you have finished, you will deliver the seminar deliverables.
The final grade is obtained in the same way as in the continuous assessment: the exam counts for 85% of the final grade and the deliveries count for 15%.
If the overall grade does not reach 5, there is a retake exam. The deliveries mark cannot be recovered. The retake is done together with the continuous assessment.
The review of the final grade follows the same procedure as for continuous assessment.
The same non-assessable criterion will be applied as for continuous assessment.
