Objectives

JUSTIFICATION:
Engineers use cientific knowledge to build machines, structures and systems that are useful and needed for humans. That is only possible if they understand and master the fundamental laws that describe the behaviour of physical systems. In this curricular unit we introduce the phenomena and laws of three fundamental areas in Physics: Waves, Direct Current Circuits and Thermodynamics and Heat Transfer.

COURSE GOALS:
- To show how to use the laws of these areas of physics to compute relevant quantities.
- To show how the physical concepts explain natural phenomena and how they are used in engineering problems.
- To measure physical quantities and verify some important laws.
- To develop critical thinking by solving problems, and analysing the results of experiments.
- To develop curiosity for the laws of nature.
- To show why engineers should respect the laws of nature.

Learning outcomes and competences

At the end of this course the studentes should be able to

- Describe the principal concepts and basic physical phenomena of waves ,  circuits, thermodynamicas and heat transfer using the right vocabulary.

- Identify the quantities, laws and concepts involved in natural phenomena and in engineering applications. Recognize the relevant physical laws in lab experiments.

- Compute relevant physical quantities in new situations. 

-Solve problems.

- Work in group.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Sudentes should have the basic knowledge of integral and differential calculus and of the Newton laws od classic mechanics.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
Engineers use scientific knowledge to build machines, structures and systems that are useful and needed for humans. That is only possible if they understand and master the fundamental laws that describe the behavior of physical systems. In this curricular unit it is introduced the phenomena and laws of  fundamental areas in Physics such as  waves, electric circuits; thermodynamics and heat transfer.

Teaching methods and learning activities

The theoretical classes will be dedicated to the presentation of subjects, starting from the phenomenological aspects to the physics models and laws explaining them. Simple experimental demonstrations and computer animations/simulations are favored to formal theoretical deductions.

The practical-theoretical classes are composed of at least two of the following components:
• Resolution of important examples to improve the understanding of the theoretical lectures (30 min maximum);
• Problem solving by the students, individually or in group, under the guidance and supervision of the professor(1h00 to 2h00);

In the context of the continuous assessment, three of these classes will be held in laboratories where the students will carry out simple experiments, analyse their results and produce a short written report.

All the support to the course, from the electronic publication of summaries, lecture notes, problem sheets to be used in theoretical-practical classes, guidelines for experiments, resolutions/corrections and results of the distributed grading assignments, etc, up to the contact with the teachers, in online forums, will be conducted through the e-learning facility Moodle@FEUP, in the are of the course (http://moodle.fe.up.pt/course/view.php?id=206), in which the students should verify their enrollment.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Students are encouraged to identify the quantities, laws and concepts involved in natural phenomena and in engineering applications, work in group, recognize the relevant physical laws in some simple lab tests.

Eligibility for exams

“Achieving final classification requires compliance with attendance at the course unit. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded. The following cases are exempted from the attendance requirements: i) cases prescribed by law, including student workers; ii) students who were admitted to exams in the previous academic year.”

The 3 lab classes are compulsary to be addmitted in the final exam.

Calculation formula of final grade

Final classification formula is given by

CF=FE*0,725+AD*0,275

FE=Final Exam

AD= 3 TPL  + ITM

TPL: Laboratory experiments in group - 4.5 points out of 20

ITM: individual tests on Moodle for self-assessment - 1 point out of 20


Only students with a minimum of 8,0 (out of 20 ) in the FE will pass the course.   

Observations

- It is advisable a weekly minimum home work of about 3h00.
- Attendance to all classes is  advisable.
- The use of a forms and a scientific calculating machine are allowed in all exams and tests of the course.

Programable/graphical calculators are not allowed during the exams and tests.
