Physics I

Theoretical lessons are aimed for theoretical exposition of the syllabus, and, whenever appropriate, are accompanied by illustrative examples intended for the consolidation of the subjects taught, which is further
accomplished in tutorial supervision lessons, aimed for solving problems related to the syllabus. In the laboratory classes, students perform, in groups, four practical works related to the syllabus (surface tension,
statics, fluid dynamics and rotation dynamics).
Evaluation of acquired knowledge consists of a laboratory component (P) with a maximum classification of 4 points, and a written evaluation component (E) classified for 20 points, which consist of the examinations in
force in the evaluation regulation of ISEC. Approval in the curricular unit is obtained if the classification in the laboratory component is equal to or greater than 2 points and the final classification, computed as 0.8*E+P, is
equal to or greater than 9.5 points.

This course aims to provide students with knowledge in some areas of physics with particular importance in the field of Biomedical Engineering. The afore mentioned knowledge is fundamental to a better understanding of
some biological processes as well as the principles of operation of several medical and biomedical instrumentation for measuring biological parameters.
Thus, students should acquire skills in the fundamental principles and laws in the different areas of physics taught, learn to apply the acquired knowledge in concrete practical situations, as well as interpret and discuss
the physical meaning of numerical expressions and results of laboratory experiments.

Mechanics of the material point and systems of points (linear momentum and collisions? Newton’s Laws? torque and angular momentum? centroid, center of mass and gravity, conservative and non-conservative
forces, work of a force, potential, kinetics and mechanic energies, the kinetic energy theorem).
Fluid mechanics (ideal and real fluids? Pascal’s Laws? impulsion? continuity and Bernoulli’s equations? viscosity, Poiseuille’s equation, Stokes Law? Reynolds number and flow regimes).
Surface phenomena (surface tension? cohesive energy and contact tension? capillarity? interfaces between immiscible fluids).
Transport phenomena (1st and 2nd Fick’s Laws, diffusion through membranes).
Thermodynamics (temperature and Zero Law, kinetic theory of gases, heat capacity and specific heat, work and heat in thermodynamic processes, 1st and 2nd Laws of Thermodynamics, reversible and irreversible processes, Carnot engines).
