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.

Subject´s presentation will be held in lectures. Recitation classes are designed to review general concepts from lectures and to solve problems.

In addition to face to face lectures, recitations and laboratory classes, didactic contents will be made available in Moodle Platform. Associated with this didactic contents, formative tests will also be available.

Particular emphasis will be 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.

- Students should bring to class a logbook exclusively for recording and processing of experimental data and calculations of uncertainties.

- The teacher may check the contents of the logbook at any time.

Eligibility for exams

ATTENDANCE POLICY

A. Attendance at laboratory and recitation classes is mandatory. Failure to attend three-quarters of the provided recitations or laboratory classes result in a RFF grade (“reprovado por falta de frequência”). This rule does not apply to students who have obtained a waiver attendance.

B. Taking mini formative and formative assessment tests are mandatory. A grade of RFF (“reprovado por falta de frequência”) should be awarded for those students failure three-quarters of the provided tests.

C. There is a minimum grade of 7 (seven) for L_AC (see “Fórmula de cálculo da classificação final”).

 

Waiver attendance at recitation and laboratory classes

A) Students who had a positive attendance (achievement) in the previous years 2013/14 or 2014/15:

i) and had a positive grade in the L_AC component, may request waiver attendance for laboratory classes.

ii) may request waiver attendance for recitation classes.

iii) and don´t request a waiver attendance for recitation and laboratory classes should attend these classes. Failure of this requirement results in a RFF grade.

B) Worker students (first enrolment) may request a waiver attendance only for recitation classes.

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 – lecture and recitation exam grade

L_E – laboratory exam grade

L_AC – laboratory continuous grade

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

If the final grade value (NF) ≥ 9.5  then the student passes.

If 8.0 ≤ NF < 9.5 students may request an oral examination.

 

The final grade (NF) for waiver attendance students is obtained by:

NF=0.90*(TTP_E) + 0.10*(L_E)

where

TTP_E – lecture and recitation exam grade

L_E – laboratory exam grade

If the final grade value (NF) ≥ 9.5 then the student passes. 

If 8.0 ≤ NF < 9.5 students may request an oral examination.

 

Observations

Any omissions and/or questions regarding this form will be resolved by the course’s instructor.

The jury can demand that the student takes an additional written and/or oral examination.
