Prerequisites for admission
Elementary algebra; trigonometry; logarithms; functions and their properties; derivative and definite integral (their geometric interpretation and physical meaning).
These concepts should already be acquired by the first semester mathematics course.

Teaching methods
The course includes lectures with exercises. The lessons will be carried out with the help of slides.
The slides of the course will be made available on the Ariel website of the course, at the end of each lesson / topic; They will NOT be provided in advance of the lessons.
Exercises are proposed at the end of each topic treated so that students can better understand the subject matter and practice in view of the final exam.
Attendance of lectures and exercises is strongly recommended.
Students with SLD or disability certifications are kindly requested to contact the teacher at least 15 days before the date of the exam session to agree on individual exam requirements. In the email please make sure to add in cc the competent offices: [email protected] (for students with SLD) o [email protected] (for students with disability).

Teaching Resources
The whole program is covered in several textbooks.
There is no preference.
As a discursive book we highly recommend Lev D. Landau, Evgenij M. Lifsits "Physics for all"
Recommended university-level texts:
- Giancoli, "Physics", or "Physics with Modern Physics"
- Halliday, Resnick, Walker, "Fundamentals of Physics";
- Jewett, Serway - "Principles of Physics".
The texts are available in university libraries, and are new and used in bookstores.
The teaching slides will be made available but do not replace the study on a textbook, even different from those recommended, even for secondary school.
There are no differences between "attending" and "non attending" students.

Assessment methods and Criteria
The exam consists of a written test lasting 2 hours, with exercises and possibly simple theoretical questions, and an oral interview.
The grade of the written exam is published on the Ariel website using the matriculation number as an identifying element in order to respect privacy.
The sufficiency of the written test (> = 18/30) allows access to the oral exam.
The oral exam is NOT confirmation of the written exam.
There are no partial tests (in itinere), but only an "exam test" that will not affect the final result.
During the written tests it is possible to consult the books, notes, forms.
The use of mobile phones or communication media with the outside is strictly forbidden.
