|MODULES||This unit is a module of:|
The fundamental aims of the course (first module 7 CFU) are focused on discovering the quantitative relationships between observations of natural facts and their models, and on learning the physical basis of phenomena in mechanics, thermodynamics, electromagnetism and optics. Emphasis is done on the ability to observe natural facts, define and quantify the quantities involved, relate these ones to models and ideas that enlight the reasons why phenomena occur and the way in which they happen. The activities and objectives of the course are integrated with the module dedicated to the general physics laboratory (second module - 5 CFU) where the phases of observation and quantification of phenomena are more developed.
The expected results are: ability to observe, quantify, model and predict natural facts in the fields of mechanics, thermodynamics, electromagnetism and optics.
The course is carried out with lectures and classroom exercises on the topics indicated in the program. Experimental demonstrations in the classroom to support the theoretical lessons may be carried out according to the availability and possibilities of teaching aids. The recommended texts are the basic reference for study and exercises. The topics covered in the lectures will be published in the form of notes on the aulaweb site.
Course program is divided into Mechanics, Thermodynamics, Electromagnetics and Optics.
