Mechanics B

Objectives

The objectives of the theoretical and exercise lectures are: 1) improve the understanding of the concepts associated to basic laws of mechanics; 2) use accurate scientific language; 3) formulate and solve, systematically, real word problems.

The objectives of laboratory lectures are: 1) acquire experimental skills in applied physics, with particular emphasis in mechanics; 2) acquire and process experimental data; 3) write scientific reports.

Teaching method

The course is organized in lectures where the theory is presented, problem-solving sessions where problems are discussed with the instructor, and laboratory sessions.

Evaluation method

Assessment Methods

The assessment in “Mechanics” fits into the Continuous Assessment type on a scale of 0 to 20 values.

Theoretical Component:

The theoretical component classification (NT) is the arithmetic average of the marks obtained in the 2 tests or the classification of the final exam. All ratings will be rounded to the nearest tenth.

Students who obtain an NT rating equal to or greater than 9.5 will pass the theoretical component.

In tests and in the Exam, the use of non-programmable calculating machines may be allowed.

Theoretical-Practical Component:

Active participation in at least 2/3 of the theoretical-practical classes (problems) from the 2nd class onwards is mandatory. Justifications for eventual absences from theoretical-practical classes will not be accepted. Students must manage the possibility of not being able to attend 1/3 of the classes in order to be able to use these absences for eventual commitments or imponderable situations, including occasional situations of illness.

The classification of the theoretical-practical component (NTP) is assigned by solving randomly generated problems in the Moodle platform (0-20 values).

All NTP ratings will be rounded to the nearest tenth.

Practical Component:

Active participation in at least 2/3 of the laboratory classes is mandatory. Justifications for eventual absences from theoretical-practical classes will not be accepted. Students must manage the possibility of not being able to attend 1/3 of the classes in order to be able to use these absences for eventual commitments or imponderable situations, including occasional situations of illness.

In laboratory classes, students will carry out 5 assignments (TL) and fill in the respective registration sheet. A complete report of one of the performed TLs will be delivered, which will be assigned a rounded classification to the units (NRel). The remaining TL will be assigned a classification (NTL) rounded off to the units.

The classification of the practical component (NP) is the result of the following weights, rounded to units:


NTL is 70%;
NRel is 30%;


Students who obtain an NP rating equal to or greater than 9.5 are approved in the practical component.


Attendance

Students who pass the practical component and who participate in the minimum number of classes required, obtain attendance in the curricular unit.

The frequency obtained within the two previous academic years is valid in the current academic year.

Final Grade

The final grade of students is the result of the following weightings approximated to the units:

NT is weighted to 50%;
NL is weighted to 25%;
NTP is weighted to 25%.


Students who pass the UC with a final grade higher than 16 on the theoretical component are admitted to an oral test.

In the oral test, students can raise or lower the final grade with the guarantee of a minimum classification of 16.
The absence of the oral test translates the acceptance by the student of the final grade of 16.
