PHYSICS

The course is classified as one of the basic educational activities for the Bachelor Degree in Science and Technology for the . It is aimed first of all at acquiring the knowledge and the comprehension of the main physical phenomena. The acquired skills are fundamental for the later part of the Degree, in particular the capability of using logical-deductive reasoning.

The instructional goals of the course are:
1) Development of the capability to solve classical Mechanics and Thermodynamic problems, by applying their main laws;
2) Stimulating the use of a correct logical-deductive reasoning in the resolution of problems and in general within the activities related to the learning;
3) Development of the capability to present, in oral and written form, concepts and scientific reasoning in a formal and rigorous way;

1. Knowledge and understanding
1.1. To know and understand the main physics laws concerning the classical treatment of physical phenomena.

2. Capability of applying knowledge and comprehension
2.1. To use the learned physical laws and concepts for the resolution of theoretical or practical problems, with a logical and deductive approach.
2.2. To know how the learned concepts may find application in the study of systems in the environment.

3. Judgment
3.1. To evaluate the logical consistency of the results arising from the application of the learned physical laws.
3.2. To critically evaluate and recognize the presence of mistakes, by a correct evaluation of the method used and of the numerical results.

4. Communication skills
4.1. To communicate both the knowledge and the effects of its applications using a proper scientific language.

Having achieved the learning objectives of the fundamental course in Mathematics. In particular, the student is expected to be familiar with the mathematical concepts of a function, vectorial function, composition of vectors, operations between vectors, limits, derivatives, integrals, trigonometry and basic differential equations.

Any university-level physics textbook is suitable. Two examples are:

P. MAZZOLDI, M. NIGRO, C. VOCI: Fisica, Volume I, EdiSES, Napoli.
P. MAZZOLDI, M. NIGRO, C. VOCI: Fisica, Volume II, EdiSES, Napoli.

These textbooks present in-depth discussions of the physical phenomena that are at a higher level than expected by a first-year student; only the material discussed during the lectures will be required to successfully complete the exam.

The method used to assess the acquired knowledge and skills consists of a written exam, with numerical and reasoning problems. An optional oral examination may be done to try to improve the final grade or to reach the minimum grade.
The written exam consists of a series of exercises, to be numerically solved justifying the used methods. The student has to demonstrate both to have acquired the concepts provided during the class and to be able to apply them coherently in the problems resolution. The duration of the written exam is 2 and 1/2 hours. During the written exam, the use of a scientific calculator and of a formulae sheet is allowed, but the use of notes, textbooks and electronic devices is prohibited.
The exam is passed with a minimum acceptable grade of 18/30 and a highest achievable grade of 30/30 (possibly cum laude).

The teaching activity is organized as lecture-style presentations at the blackboard.

Furthermore, in the moodle platform of the University will be present the possible didactic material presented as well as powerpoint projections in the classroom, as well as solved examples of previous exams.
