Objectives and Contextualisation
The main objective of the course is that the student acquires the basic knowledge of mechanics and waves both conceptually and mathematically. Special emphasis will be placed on the qualitative and quantitative understanding of the phenomena and laws that will be relevant later in the field of Nanoscience.
Competences
- Apply the concepts, principles, theories and fundamental facts of nanoscience and nanotechnology to solve problems of a quantitative or qualitative nature in the field of nanoscience and nanotechnology.
- Apply the general standards for safety and operations in a laboratory and the specific regulations for the use of chemical and biological instruments, products and materials in consideration of their properties and the risks.
- Communicate orally and in writing in one's own language.
- Demonstrate knowledge of the concepts, principles, theories and fundamental facts related with nanoscience and nanotechnology.
- Handle the standard instruments and materials of physical, chemical and biological testing laboratories for the study and analysis of phenomena on a nanoscale.
- Interpret the data obtained by means of experimental measures, including the use of computer tools, identify and understand their meanings in relation to appropriate chemical, physical or biological theories.
- Learn autonomously.
- Manage the organisation and planning of tasks.
- Obtain, manage, analyse, synthesise and present information, including the use of digital and computerised media.
- Reason in a critical manner
- Recognise and analyse physical, chemical and biological problems in the field of nanoscience and nanotechnology and propose answers or suitable studies for their resolution, including when necessary the use of bibliographic sources.
- Recognise the terms used in the fields of physics, chemistry, biology, nanoscience and nanotechnology in the English language and use English effectively in writing and orally in all areas of work.

Methodology
The course includes theory classes, exercises classes and laboratory work.
In the theory classes the contents of the subject will be discussed, always encouraging the participation of the student by asking questions.
In the classes of exercises it is intended that the student participates in an active way either posing doubts or participating in the resolution of exercises and questions.
Some of the sessions of exercises, if the pandemic allows, will be of guided problems type, where the students will solve the problems with the help of the teacher and at the end of the class they will have to deliver individually some solved questions on the problem solved.
The attendance to the laboratory is compulsory and there will be four sessions of three hours each in which students in groups of three people will have to make a series of experiments related to the concepts discussed in the classes of theory and exercises.
The first practice, to be carried out by all groups, will be "Instrumentation: length and mass measurements and error calculation" (P1). Each student, on an individual level, will have to prepare a report of this practice, which will be delivered through the virtual campus at the latest two weeks after the lab session.
The students will have to do three more practices between the following four:
P2: Free fall
P3: Waves and sound
P4: Energy conservation
P5: Movement of projectiles
A collective report (one per group) will be delivered through the virtual campus, which will also be delivered no later than two weeks after the corresponding lab session.
The material for theory classes, exercises and laboratory work will be provided through the virtual campus of the subject.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The final grade of the course will be obtained from the following percentages:
- 35% : Mark of the first partial exam.
- 35% : Mark of the second partial exam.
- 20% : Mark of the delivered laboratory reports.
- 10% : Mark of the delivered activities.
In order to apply these percentages, the score (out of 10) of each of the partial exams must be equal to or higher than 4 and all the laboratory work must have been carried out. In the case that in one or both of the partial exams, the mark is lower than 4, the student will have to take the retaking exam of the part that has been failed with a mark lower than 4. If a student, even if he/she has passed the subject, wants to improve the mark of the written exams, he/she can take the retaking exam of the part he/she wants to improve and the final mark that will be considered will be the mark obtained in the retaking exam. The mark will be "no avaluable" when the student does not take any exam or only takes one of the two partial exams and does not attend the retaking exam.
