Learning objectives
The Course of Physics has the goal to propose the base knowledge of Physics, preparatory to the professional branches of one agriculture University Faculty.
More generally, the goal of the Physics is to gain a deeper understanding of the world in which we live.
Physics is the study of fundamental laws which, simply, are the laws that underlie all physical phenomena in the universe: there is a great beauty the vision of our quotidian reality compared to the completeness and variety of the whole Universe.
Obviously, these laws are expressed by mathematical forms, therefore it is request a solid preparation of the Base Mathematics.
It must be enphasized that the methodology adopted is "Problem Solving in Physics", which means to go beyond passive reading, to interact with Physics and experience it by doing and solve problems.
Expected learning outcomes
The student obtain the knowledges requested to tackle and solve strictly simple problems of Physics applied in the different branches of learning and, later on, when the Student will be directly involved after entering in the working activity.
The Student will be able to:
· Understand carefully the problems to deal
· Sketch the system, by means of personalized drawings and models
· Strategize the solution of the problems
· Identify the metodologies and equations to carry it out
· Solve the equations and develop calculations
· Check the results: are they reasonable, are the numerical values reasonable?

Prerequisites for admission
A solid foundational preparation in the scientific subjects (Mathematics and Physics), acquired through the standard curricula of various high schools, is desirable. The course is conceptually subsequent to the first-year university Mathematics course, whose contents are preparatory for the topics to be addressed.
Teaching methods
Physics, like other scientific disciplines, finds strong support in the daily observation of natural phenomena and technological applications. Therefore, the topics covered will be applied to real-world situations, fostering problem-solving activities and the application of learned concepts to solve problems that are highly relevant to everyday life. Furthermore, the NOS approach to teaching physics is employed, according to which, for effective learning, it is essential to integrate purely scientific concepts with their economic, technological, social, and ethical implications, following a historical and logical approach in presenting the content that also highlights the personalities and cultural contexts within which these physical concepts were developed. Laboratory activities will be a cornerstone of the educational journey, in order to develop practical skills and the application of concepts.
Teaching Resources
In addition to the lecture notes provided by the professor, various textbooks already used in the final three years of high school can be utilized. However, the following are recommended:

James S. Walker - Theoretical Models and Problem Solving
Ugo Amaldi - Amaldi for Scientific High Schools*
Assessment methods and Criteria
The exam consists of a written test divided into two parts and a final oral examination. The two written tests can be taken at different times and not necessarily sequentially. Admission to the oral examination implies passing both written tests with a score of at least 16/30. Each written test consists of 5 problems and an open-ended in-depth question. The subject matter of the problems and the in-depth question will be published in advance on ARIEL, based on the schedule of the lessons. Oral examination: it develops from one of the open questions provided in the written tests, followed by a discussion and a deeper exploration of the written tests.
