Activity type
WRITTEN TEST
Prerequisites
Topics already learned at the high school such as: the concept of equation and the basic rules for its solution, the representation of digits in the scientific notation as power of ten with positive and negative exponent; logarithms and their properties; the definition of function; the cartesian representation of a graph of a straight line, a parabola, a hyperbola and an exponential function; the trigonometric functions; the measure of the angle in radiants; the surface areas and volumes of some geometrical figures (triangle, rectangle, circle, cube, sphere)
Learning outcomes
The aims of the course are:
1) to instill in the student the fundamental topics of Physics for the comprehension of biological and biomedical phenomena
2) to impart the meaning of scientific method
3) to teach the student how to apply the principles and law of Physics to specific problems, in particular the biological and biomedical ones
At the end of the course the students must be able to:
1) find the fundamental physical quantities which are involved in the description of a physical phenomenon
2) schematize the physical phenomenon with a model which could represent the fundamental characteristics of the system under study
3) formulate physical laws of the system under study, if they derive from general principles or they are of empirical origins, and represent them in an analytical or graphical form
4) analyze from a quantitative point of view the inter-dependence among two or more physical quantities
5) integrate all the knowledge acquired for the resolution of a specific problem
