Learning outcomes of the course unit
The course gives, with a simplified approach, some basic concepts which are necessary to some of the following biology and chemistry courses. In particular, the contents of the present course offer a physical description of the mechanisms underlying many processes relevant for chemistry and biology.
Knowledge and understanding
The student should prove to be able to know and understand some of the most important aspects of classical physics, and of the physical laws controlling them.
Applying knowledge and understanding
The student should be able to understand similarities and differences between physical systems, and to comprehend physical laws. The student should be able to comprehend the essential aspects of physical laws, perform independently simple exercises, analyze the data and summarize the problems in their essential aspects.
Basics of arithmetic, algebra and calculus
