Teaching languages


This subject has been successfully enrolled by a number of foreign students, most of them from Italy. Classes are taught in Catalan, and students are expected to achieve a basic understanding of spoken Catalan. However, exams and practical reports can be written in Italian or other languages. Public questions in the classroom, and private questions to the lecturer, can also be posed in Italian or other languages.

Skills


Basic skills
  • B4_That students can convey information, ideas, problems and solutions to both specialized and non-specialized audiences

     

Specific skills
  • E2_Understand and master the fundamental concepts of the general laws of mechanics, thermodynamics, fields and waves and electromagnetism and their application in solving engineering problems

Description


Introduction to general physics, emphasizing those aspects that may be more useful for later subjects. The contents are complemented with those of the subject of Physics 2.

Learning outcomes


In general, this subject contributes to the following learning outcomes specified for the subject to which it belongs:

  • Understand and use the basic laws of mechanics.
  • Determine the equilibrium state of a solid.
  • Understand the basic principles of electrostatics.
  • Solve direct current circuits.
  • Measure the values ​​of the electrical quantities in a direct current circuit.

At a more specific level, at the end of the course the student must be able to:

  • LO1. Understand and use the basic laws of mechanics.
  • LO2. Understand the basic principles that govern mechanical equilibrium in rigid solids and apply them in simple technical problems.
  • LO3. Understand the basic principles of electromagnetism. Analyze electric and magnetic fields and apply them to the resolution of electrical circuits.
  • LO4. Understand and use the basic knowledge of thermodynamics.
  • LO5. Take experimental measurements.
  • LO6. Analyze and critically discuss the results obtained.
  • LO7. Solve problems related to basic concepts.

Working methodology


The course combines face-to-face classes in the classroom in a large group and practical classes in the laboratory in a small group.

In the classroom, the presentation of the theoretical concepts, the resolution of exercises and examples of application by the teacher will be alternated, and occasionally, the collaborative resolution and presentation on the board of some exercise by the students. students.

In the laboratory the students, in groups of two or three, will carry out experiments related to the contents of the subject.

Students will have to devote additional time, non-contact, to the resolution of exercises, preparation of reports of laboratory practices and preparation of written tests.

Learning activities


1. Laboratory practices

General description

Measurements and observation of various experiments in the Physics laboratory.

Support material

Practice scripts provided by the teacher.

Deliverable and links to the evaluation

Preliminary calculations when necessary.

Report of each practice with the results of the measures and the conclusions of the student.

The qualification of the practices will represent 30% of the note of the course.

Specific objectives

Perform theoretical calculations and take various measures for experimental verification.

Treat the experimental measures: calculation of errors and interpretation of the graphical representations. Draw conclusions from them.

 

2. Resolution of exercises

General description

Some of the proposed exercises will have to be solved.

Support material

Collection of exercises.

Notes, books and other supporting material.

Deliverable and links to the evaluation

Generally these exercises will have to be solved outside the classroom. Some of them will be solved by the students in the classroom, collaboratively in groups of two or three students, and displayed on the board.

This activity will not directly contribute to the course grade. However, its realization will be very useful for the preparation of the written tests.

Specific objectives

Solve exercises related to the contents of the subject.

 

3. First partial test

General description

Written test to evaluate the contents developed in the first half of the course.

Support material

Statement of the test.

Deliverable and links to the evaluation

Test resolution.

The grade will represent 35% of the course grade.

Specific objectives

Solve exercises and explain theoretical concepts corresponding to the first half of the subject.

 

4. Second partial test

General description

Written test to evaluate the contents developed in the second half of the course.

Support material

Statement of the test.

Deliverable and links to the evaluation

Test resolution.

The grade will represent 35% of the course grade.   

Specific objectives

Solve exercises and explain theoretical concepts corresponding to the second half of the subject.

 

Evaluation system


The final grade will be the weighted average of the grades of the assessable activities:

First partial test: 35%

Second partial test: 35%

Laboratory practices: 30%

Recovery exam: 70%

There will be a first partial test in the middle of the course and a second partial test at the end of the course.

For students who do not pass the assessment during the course, 30% of the internship grade will be maintained, and an overall retake exam will be held which will be worth 70% of the grade.

The resit exam may be used to pass the subject with a final grade of 5, but not to obtain a grade higher than 5.

In the event that the health regulations prevent a first face-to-face examination, the weighting of the evaluable activities will be:

Face-to-face final test: 70%

Laboratory practices: 30%
