(objectives)
The course aims to provide the necessary elements for understanding the natural physical phenomena and their laws. It is focused on the concepts necessary for a better understanding of the arguments that students encounter in their carrier. This should help them to grasp the importance of this discipline in achieving a deeper understanding of topics relevant for the analysis and the management of mountain areas.
Knowledge and understanding
The course aims to provide a critical understanding of the principles of Classical Physics (mechanics, fluids, thermodynamics and calorimetry, electromagnetism and waves) necessary for comprehending many phenomena specific to mountain areas and the instrumentation used in the field today.
At the end of the teaching period, students will be able to:
analyze a problem, identifying the involved physical phenomena;
identify the essential elements of a physical phenomenon: the physical quantities involved and the laws governing it
classify physical phenomena and compare them, highlighting analogies and differences
Applying knowledge and understanding
At the end of the teaching period, students will be able to:
address problems related to the covered areas of Classical Physics and develop appropriate solution strategies
connect acquired knowledge to solve complex problems involving different physical phenomena
apply acquired knowledge and use the scientific method to address problems typical of mountain areas
Making judgements
At the end of the teaching period, students will be able to independently further develop insights on the topics covered.
Communication skills
At the end of the teaching period, students will be able to:
present scientific arguments in a clear and rigorous manner;
organize contents logically;
use proper terminology and appropriate technical-scientific language
Learning skill
At the end of the teaching period, students will be able to identify the necessary information to deal with the study of topics related to the analysis and management of mountain areas involving physical phenomena.
