Learning objectives
The aim of the course is to provide the fundamentals of mechanics, thermodynamics and electrology, with paricular emphasis on the development of a rigourous scientific method, both at a theretical level and to solve simple physical problems. The goal of the course is also to help the understanding of the specific topics of subsequent courses.
Expected learning outcomes
Knowledge and skills necessary for the correct interpretation of the most important physical phenomena and of the laws related to them. Ability to approach and solve numerical exercises, with the relevant mathematical tools, and to understand graphs of physical quantities. The student will also be able to describe with the appropriate language the basic physical phenomena.
Single course

This course can be attended as a single course.

Course syllabus
Introduction to Physics
- Fundamental units of the International System, prefixes, derived units, dimensional analysis.
- Scalars and vectors, scalar product (expressed analytically by components or geometrically).

Kinematics
- Motion in one dimension: position and displacement, speed, acceleration, uniformly accelerated motion, free fall
- Multi-dimensional motion: trajectory, uniformly accelerated motion, uniform circular motion, angular velocity and angular acceleration

Dynamics
- Newton's laws: concept of force and mass, equations of motion, action and reaction
- Examples of forces: gravity force and constant g, elastic force, centrifugal force, static and dynamic frictional force.
- Work performed by a force, conservative forces, potential and kinetic energy, energy conservation
- Collisions and momentum conservation
- Law of universal gravitation, gravitational force between spherical objects

Fluid mechanics
- Definitions of density and pressure
- Stevin's law, Pascal's principle and Archimedes' principle
- Bernoulli equation
- Ideal and non-ideal fluids: viscosity, capillarity and surface tension

Thermodynamics
- temperature and heat
- phase transitions
- principles of thermodynamics
- thermal machines and Carnot cycle
- ideal gas and kinetic theory of gases

Basics of electromagnetism
- electric charges and Coulomb's law
- Electric field, electric potential and electric potential energy.
- Capacitors, resistors and direct current circuits
Prerequisites for admission
Elementary algebra; trigonometry; logarithms; functions and their properties; derivative and definite integral (their geometric interpretation).
It is strongly recommended to have followed the lessons of the "Mathematics" course of the first semester (and possibly to have taken the related exam).
Teaching methods
32 hours of theoretical lectures and 32 hours of exercises.

Both the theoretical lessons and the exercises will contribute to achieving the expected results of the course, that is, to understand the fundamental physical laws that describe nature, and to use this knowledge to solve simple physical problems.
The slides shown during the theoretical lectures and the texts of the problems covered during the exercises will be available on the Ariel website.
Teaching Resources
James S. Walker, Fondamenti di Fisica, Casa Editrice Pearson, 6ª edizione. The course will be based on this book. Any other university textbook about general physics could be useful.

The slides shown during the theoretical lectures and the texts of the problems covered during the exercises will be available on the Ariel website.
Assessment methods and Criteria
The written exam will be divided into two parts. In the first part, students will be provided with a questionnaire with 10 simple questions with closed or open answers on topics covered during the lessons. After 40 minutes the questionnaire will be withdrawn.
The second part of the exam will consist of some problems (more complex than the previous ones) on different topics covered in the course, to be carried out over a longer time (generally a hour and a half).

The evaluation of the exam will focus both on the formal correctness of the solutions to the proposed problems and, when required, on the contextual and appropriate description of the corresponding physical phenomenon.

To attend the written test, students must be enrolled regularly through SIFA and must be in front of the classroom 15 minutes before the beginning of the written test, with photo ID and protocol sheets.
During the whole written test it is not allowed to use books or notes. In the second part of the exam only, the use of the cheat sheet provided by the teacher is allowed.

Students who will have obtained a score equal to 16/30 or 17/30 at the written exam will be allowed to take an oral exam to reach (or pass) the sufficiency (18/30).
Students with a grade equal to or greater than 18/30 can at their discretion take an oral exam or simply confirm the grade of the written exam.

Two "in itinere" tests will be organized during the course, and these will be structured as the written exams just described (first part with 10 simple questions and second part with more complex problems to be solved). Each "in itinere" test will be considered passed if a score greater than or equal to 16/30 is obtained. The total score will correspond to the arithmetic mean of the scores of the two tests.
Also in this case, students who obtain an average score equal to 16/30 or 17/30 will be allowed to take an oral exam to reach (or pass) the sufficiency (18/30).
Students with an average score equal to or greater than 18/30 can at their discretion take an oral exam or simply confirm the grade of the written exam.

The communication of the passing of the written exam (and of the "in itinere" tests) and the schedule of the oral exams, will be given via email and via the Ariel portal.
The oral exam (if taken) will contribute to a maximum of 20% to the final grade. The final grade of the exam will be expressed in thirtieth.

Students with specific learning disabilities or other disabilities are requested to contact the teacher via email at least 15 days before the exam session to agree on any personal compensatory measure. In the email addressed to the teacher, the respective University services must be reported in CC: [email protected] (for students with LD) and [email protected] (for students with other disabilities).
