Objectives

Physics:
This course has the primary objective to provide the knowledge on the basic laws of Physics and the capacity (i) to apply them to explain the main phenomena of biological and medical interests; (ii) to get the necessary background to explain the functioning of the human body and the sources of some pathological conditions. We refer to the next section for a more detailed list of topics covered

Prerequisites

Prerequisite of the course: Elementary Mathematics and Physics (as taught in high schools)
Physical quantities and the systems of measurement. Kinematics and Dynamics of point particles. Work and energy. Static of fluids. Thermology, ideal gas law, 1 e 2 principle of thermodynamics. General phenomena in acoustic and optics: reflection, refraction, simple lenses and mirrors. Introduction to electrostatic and electrodynamic: Coulomb law, electric field and potential, capacitors, elementary circuits, continuous currents, electrical resistance, Joule effect, power generator.
Natural, integer, rational and real numbers and their operations. Order of magnitude and scientific notation. Proportions and percentages. Power with integer and rational exponent and their properties. Logarithm (10 and e base) and their properties. Algebraic expressions and polynomials. Equations and inequalities of first and second degrees. Elementary functions and their graphical representation.
Polygons, circumference and circle, sphere and spherical surfaces. Angles in degree and radians. Sinus, cosinus and tangent, trigonometric equations and application to right triangles. Cartesian coordinates in two and three dimensions. Equation of a straight line. Probability, frequency and average value.

Teaching Methods

Physics:
Combination of classroom teaching and interactive teaching with the use of tools and a variety of media in the classroom (video projections and blackboard).

Informatics:
Moodle e E-learning

Verification of learning

Informatics:
mandatory exercises and audits

Physics:
mandatory written exercises on the basic topics followed by audits on applied physics. During the teaching period two written exercise sessions can substitute the exercises before the audits.
