Mechanics B
Objectives
By the end of the course the student should have acquired the skills to:
 Address physical problems in the context of biological systems
 Use appropriate physical quantities to describe properties, states, interactions and events
 Formulate physics'' problems in mathematical language applied to physical quantities
 Recognize the usefulness of mathematical tools and models in solving physics'' problems
 Analyze and solve problems in the context of mechanics and biomechanics (translation and rotation of bodies)
 Associate movements under the action of forces to transferences of energy
 Describe using mathematical tools oscillatory and wave phenomena.

Teaching method
The course is organized in lectures where the theory is presented, problemsolving 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 nonprogrammable calculating machines may be allowed, as well as a manuscripted onepage A4.
Frequent questionnary will challenge the study, being available on Teams platform. Its average grading NF contributing to final grade.
TheoreticalPractical Component:
Active participation in at least 2/3 of the theoreticalpractical classes (problems) from the 2nd class onwards is mandatory. Justifications for eventual absences from theoreticalpractical 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.
Practical Component:
Active participation in at least 2/3 of the laboratory classes is mandatory. Justifications for eventual absences from theoreticalpractical 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 45 assignments (TL) and fill in the respective registration sheet. A complete report of the last performed TLs will be delivered, which will be assigned a rounded classification to the units (NRel). Protocols are to be followed for the first labs but not for the last, the students being challenged for its contents. 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:
 50% TL;
 50% Rel;
Students who attended minimum classes and obtain an NP rating equal to or greater than 9.5 are approved in the practical component. 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:
 60% NT;
 25% NP;
 15% NF.
