### Learning Objectives

The course is devoted to the presentation of the foundations of classical physics. Physics laws are proposed highlighting the experimental scientifiìc method that is the base for the study of nature's laws. Whenever possible connections with contemporary research are presented as well.

### Learning Achievements (Dublin Descriptors)

• D1 - Knowledge and understanding - The student should possess a proper knowledge of the main physical laws and of the interconnections between them, as well as of the experiments and processes leading to their formulation.
• D2 - Applying knowledge and understanding - The student should be able to apply the main physical laws to understand common natural phenomena, even when these are not directly relevant for physics but also, for example, for biology.
• D3 - Making judgements - The student must show a proper autonomy in his knowledge, not simply recalling it by heart.
• D4 - Communicaion skills -  The use of an appropriate scientific language is required.
• D5 - Learning skills - The ability of autonomous deeper study of one ore more topics is appreciated.

### 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

Lectures

Attendance

A good knowledge of algebra, trigonometry and the capability of solving equations and systems of equations is required, as well as the basic differential calculus.

Course books

Slides of the lectures.

Assessment

Oral examination, where at least three questions will be asked in order to assess the achievement of the various skills.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
