### Learning Objectives

Starting from basic concepts of classical physics, the course introduces logic and conceptual methodologies to correctely approach scientific arguments which the students will face during their academic studies and work experience.

The learning objects thus apply to the procedures of abstraction, formalization for a quantitative approach, experimental method application.

### Learning Achievements (Dublin Descriptors)

Knowledge and understanding: the student will know the main laws of Physics, particularly in the fields of point mass mechanics, of the mechanics of the rigid body and of the fluids. The student will possess basic knowledge of electrostatic and magnetism, and of electrodynamics.
Applying knowledge and understanding: the student will be in position to apply the laws of Physics to real problems, and to solve them both in a qualitative and quantitative way.
Making judgements: the students will be able to assess the plausibility of a result, both on the basis of correct units, and by means of analogical reasoning and scientific sense.
Communication skills: the student will acquire a correct scientific language, which includes the appropriate use of the units..

### Teaching, Attendance, Course Books and Assessment

Teaching

Lectures.

Attendance

For the full achievement of the didactic objectives of the course, attendance at lectures is strongly recommended, although not mandatory. Students are considered “attending” upon attaining at least 50 percent of the total number of hours in the course.

Course books

Fundamentals of Physics, D. Halliday, R. Resnick, J. Walker, Wiley

Assessment

A first partial exam will be organized about three-quarters of the way through the course. In order to take this partial exam, students must have already attended at least 50% of the hours of the entire course (i.e. 20 hours). This partial exam will focus on the syllabus taken up to that point. and will be graded in thirtieths (sufficiency with a grade >= 18/30).

Those who pass the partial exam may take a second partial exam in the final appeals. This partial exam will focus on the program taken after the first partial .and will be graded in thirtieths (sufficiency with grade >= 18/30).

The total grade will be given by the weighted average of the two grades obtained (weights equal to 3/4 and 1/4).

Students who do not take the first partial will have to take the entire exam in the final appeals

Both the partial exams and the final exam are structured as follows:

Written and oral test. The written test consists of a multiple-choice test and open-ended questions and is considered passed when a grade of 18/30 is achieved. The oral test will focus on discussion of the written test and exposition of topics covered in the course.

EVALUATION CRITERIA AND PARAMETERS

For each item, four levels of assessment are given, corresponding to: insufficient (grade < 18); sufficient (17 < vote < 24); good (23 < vote < 28); excellent (27 < vote < 31)

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.
