Learning objectives

The course aims to provide the student with fundamental knowledge of the laws of
physics and of the application of the laws to the study of the most common
phenomena in order to be able to describe and interpret investigation and
measurement techniques, which will then be used in research or working
laboratories. Particular attention will be placed on units, orders, appropriate use of
terms and development of ability to synthetize. The fundamental equations will be
explained and applied, with acknowledgement of the limits of their validity, to the
case of simple problems.
The purpose is to transfer knowledge and develop ability, to facilitate understanding at a level which, using advanced and differentiated texts, allows to approach the main themes of General Physics and then provide the basic skills to solve problems of various kinds that require a physical approach, interpret results and communicate in an understandable and correct, developing independent learning skills necessary for subsequent searches.


Attendance to the basic Mathematics course is recommended
