Fisica Generale 1 (INF)
General Physics 1 Gianni Albertini
Basics of mathematics and algebra are assumed as previous knowledge.
At the end of the course a basic knowledge of the derivatives and integrals is also assumed (either obtained through this course or in the course of Analisi Matematica or as a previo
KNOWLEDGE AND UNDERSTANDING:
This course gives students the fundamentals of the experimental method, typical of each scientific subject, and the fundamental laws of classical mechanics, thermology and part of thermodynamics. It represents a basic link between the secondary school knowledge and the university teaching. The acquired knowledge allows students to get the necessary instruments for a scientific approach to the analysis of engineering problems. CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The acquired knowledge and physic methods will allow students to understand, analyse and sketch engineering problems. In particular, students will have to acquire the ability to outline complex phenomena into their essential elements and to apply the classical physics laws to describe them. To this aim, the proposed exercises are usually derived from the common experience. Such knowledge and methods can be applied to many of the university courses the student will attend and, in the following, to the problems he will face during the working career. TRANSVERSAL SKILLS:
The methodological approach acquired and the exercises proposed during this course will contribute to improve the judgement ability, the learning skill and that of drawing conclusions.

Particle mechanics. Systems mechanics. Kinematics. Rectilinear, circular, harmonic motion. Relative motions. Dynamics. Constraints, elastic, weight and friction forces. Tension.

Development of the examination
LEARNING EVALUATION METHODS
The learning evaluation is performed by using one written and one oral tests The written examination may be replaced by two partial tests, one on the topics of the first part of the course, the other on the remaining part. Partial test are only possible until the first exam session after the course (typically by February for courses of the first semester and July for those in the second). The written test (or the two partial tests) is valid fourteen months, also for many oral tests if it is the case. The final valutation is mainly based on the oral exam.
LEARNING EVALUATION CRITERIA
The written tests give access to the oral one(s) and aim to check the ability to solve simple problems related to the course topics. The oral examinations aim to test the ability to expose a topic in a clear way, to connect different parts of the program, to use the language of Physics and the formalism of Mathematics in a way appropriate to the course level. Personal opinions, explanations, interpretations are appreciated (unless they are totally erroneous or misleading).
LEARNING MEASUREMENT CRITERIA
The examinations are considered a part of the learning process. Thus, their aim is not a simple valutation mark or a decision for passing or failing. On the contrary, they aim to suggest the parts of the program to be better understood, if it is the case, or the basics settings to be acquired. In the latter case a reworking of the entire program is usually required. Once that the preparation is satisfactory the final valutation is a mark out of 30.
FINAL MARK ALLOCATION CRITERIA
The written test gives access to the oral one(s). It aims to check the ability to solve simple problems related to the course topics. The final valutation is mainly based on the oral exam, which aims to evaluate the mastery of the course topics and the ability to explain them to other people, to connect different parts of the program, to use the language of Physics and the mathematical formalism in an appropriate way. Personal opinions, explanations, interpretations are appreciated (unless they are totally erroneous or misleading)
