Teaching language

Suitable for English-speaking students

Objectives

F155 is an introductory physics course.

Fundamental physical principles of mechanics, waves, thermodynamics, electricity and geomagnetism are covered.

 

Learning outcomes and competences

After completion of this course, the student should be able to:

- Analyze physical quantities in terms of units and dimensions;

- Analyze elementary motion problems in one, two and three dimensions. Analyze in particular projectile and circular motions.

- Apply Newton's laws of motion and the work-kinetic energy theorem in common introductory problems.

- Understand introductory concepts involved in momentum and energy conservation.

- Apply introductory principles dealing with simple harmonic motion.

- Analyze elementary problems involving laws of thermodynamics

- Understand certain elementary concepts in electricity and magnetism, including Coulomb and magnetic forces, fields, circuits and Kirchhoff’ s laws.

- Demonstrate basic experimental skills by the practice of setting up and conducting an experiment safely and efficiently and report verbally and in written language the results of the experiment.

- Demonstrate basic communication skills by working in groups on laboratory experiments and by the discussion and interpretation of experimental data and errors analysis.

Teaching methods and learning activities

 

Teaching will be done in a continuous way, both in lectures and in the remaining classes. This requires a commitment to a responsible attendance by students.

The presentation of the matter will be held in lectures. Theoretical-practical classes will address solving and discussion of problems to consolidate the taught matter.

In addition to presential theoretical (T) and theoretical-practical (TP) classes, didactic contents will be made available in Moodle Platform. Associated with this didactic contents, formative tests will also be available.

 

Particular emphasis will given to motivate students to work throughout the semester. It is considered that learning implies dedicated work and attendance of all those interested in acquiring skills.

 

 

 

LABORATORY CLASSES:

 

- Students should prepare in advance for the laboratory work that will accomplish.
- Students should bring to class a logbook exclusively for  recording and processing of experimental data and calculations of uncertainties.
- This logbook may be asked, at any time, by the teacher to assess its content.

Calculation formula of final grade

The final grade (NF) for students attending laboratory classes is obtained by

 

      NF = 0.75*(TTP_E) + 0.10*(L_E) + 0.15*(L_AC)

 

where

 

      TTP_E – theoretical and theoretical-practical exam grade

     L_E – laboratory exam grade

      L_AC – laboratory continuous assessment grade

 

There is a minimum grade of 7(seven) for each component.

 

A student with L_AC < 7.0 is excluded from final exam.

 

The final grade (NF) for students dispensed from attending laboratory is obtained by:

 

     NF = 0.90*(TTP_E) + 0.10*(L_E)

 

where

 

      TTP_E – theoretical and theoretical-practical exam grade

     L_E – laboratory exam grade

 

There is a minimum grade of 7.0 (seven) for each component

 

If NF≥ 8.0 students may request an oral examination.
