AIMS AND CONTENT
LEARNING OUTCOMES
The course provides an introduction to the phenomenology and the mathematical formulation of the laws of classical mechanics. The student will acquire the scientifictechnical methodology necessary to deal with the problems of physics in quantitative terms.
AIMS AND LEARNING OUTCOMES
The course aims to impart knowledge of the fundamental laws of mechanics. Its educational objective is to foster a deep understanding of these concepts and the ability to apply them in solving simple problems. This entails developing the skill to model problems using the fundamental laws introduced throughout the course. It is worth emphasizing that, in the realm of physics, comprehending a concept is inherently intertwined with the capacity to effectively employ it in relatively straightforward scenarios.
