### Bridging Courses

Although there are no mandatory prerequisites for this exam, students are strongly recommended to take it after Calculus. It is also worth noticing that the topics covered by this course will be used in Physics II.

### Learning Achievements (Dublin Descriptors)

Knowledge and Understanding

On completion successful students will be able to understand the basic concepts of classical mechanics and thermodynamics. In particular: Newton's laws, work, energy, conservation of energy, the principles of thermodynamics.

Applying Knowledge and Understanding

The student will be able to understand phenomena related to classical mechanics and thermodynamics and to solve simple problems on these subjects.

Making Judgements

The student will be able to recognize a physical phenomenon and the laws which govern it, to understand the most relevant physical quantities involved and to give an estimate of them.

Communication Skills

The student will have to know how to communicate in a rigorous and effective way the concepts learnt during the course.

Learning Skills

The acquired knowledge will allow the student to further study the classical physics and to apply the methodologies of physical sciences to other subjects.

### Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

### Teaching, Attendance, Course Books and Assessment

Teaching

Theory lectures and exercises, both face-to face and on-line.

Attendance

Although recommended, course attendance is not mandatory.

Assessment

Written exam and oral exam. The written exam (duration 3 hours) consists of two exercises on different subjects of the course. It is passed if the mark (which is valid for all the exam calls of the same academic year) is at least 15/30. The oral exam can be taken only if the written exam is passed. The final mark is the weighted average of the written and the oral marks with weights 1/3 and 2/3, respectively.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

### Notes

The course offers additional e-learning facilities on the Moodle platform > elearning.uniurb.it
