Prerequisites (for future units)
This unit is a prerequisite for:
The course of General Physics 2 is divided into two parts. The first part is devoted to the classical mechanics of rigid bodies, the motion in a central field (for example gravitational) and to collisions between particles.The second part is dedicated to thermodynamics, kinetic theory and fluid mechanics.
The course provides knowledge and understanding of fundamental concepts of the mechanics of many body systems (fluid and rigid bodies) and of thermodynamics, highlighting the models used and their limits of validity.
The aim of the course is to provide the students with the knowledge and understanding of the fundamental concepts in the following areas:
Newtonian mechanics of extended systems (fluid and rigid bodies)
Motion of a particle in a central field (in particular the gravitational field) and classical scattering.
At the end of the course the student will:
know and understand the contents of the course, as presented by the professors both through lectures and through any given precise bibliographical reference
be able to relate the contents of this course with the contents of the course of General Physics 1 (1st year LT), and the different contents of the General Physics 2 course among them
be able to elaborate independently thoughts on the concept of model and its limits of validity
know how to solve, both individually and in team, exercises of the type and difficulty of those presented by professors during the course
know how to discuss, with the professors and with their peers, the topics covered in the course, using a correct and scientifically appropriate language
know how to study the topics proposed, taking advantage from, and relating one to each other, different sources such as notes taken in class, bibliographic references given by the professors and any suggested research material
Students are expected to be familiar with the contents of the courses of General Physics 1, Mathematical Analysis 1, Linear Algebra and Analytical Geometry, in particular with: analysis of functions; derivatives and integrals for functions of a single variable; linear differential equations
The course is provided in the form of lectures that include:
presentation of contents on the blackboard
power point presentations
exercises done on the blackboard by the teacher
group activities (for example, exercises carried out by students in groups with the guide of the teacher, problem-based learning activities)
PART 1 (first semester)
Oscillations: 1D free oscillator, dumped oscillator, forced oscillator, coupled oscillator.
Integration of the equations of motion: motion in one dimension, determination of the potential energy from the period of oscillation, the reduced mass, motion in a central field, Kepler’s problem.
Collisions between particles: disintegration of particles, elastic collisions, scattering, Rutherford’s formula, small-angle scattering.
Motion of a rigid body: angular velocity, the inertia tensor, angular momentum of a rigid body, the equation of motion of a rigid body, eulerian angles, Euler’s equations, the asymmetrical top, rigid bodies in contact, motion in a non-inertial frame of reference.
PART 2 (second semester)
Thermodynamic systems, zero principle and temperature; heat and first principle of thermodynamics; phase diagrams and state equations; applications of the first principle to ideal gases and other systems; kinetic theory; real gases and hints on molecular interactions; second principle of thermodynamics; thermal machines; thermodynamic potentials and thermodynamic equilibrium; coexistence between phases and phase transitions, Clausius-Clapeyron equation; black body radiation and heat transmission.
Static and dynamic of pure homogeneous fluids.

Ongoing evaluation and final written and oral examination.
The final grade is the result of the overall evaluation (in the sense specified in the following points) of the ongoing evaluation and of the final written and oral tests.
During the first and second semester, ongoing activities will be proposed such as: homework, group activities in the classroom, Problem Based Learning type activities. The activities evaluated during the course have several objectives, including: helping students to gradually understand what teachers' requests are (training objectives and expected learning outcomes); encouraging a constant study commitment during the entire duration of the course; favoring an overall assessment that is less subject to emotional factors or elements of chance; developing soft skills such as the ability to work in a team, the ability to self-organize, the ability to write short reports on the work done ...
FINAL WRITTEN TESTS (PARTIAL AND COMPLETE)
Complete written exam (open to all students)
The complete written test consists of four exercises (2 for each part of the course). The time available to carry out the test is 4 hours. The written exam is passed if the complete test is assessed with a score of at least 18/32.
Partial written tests (reserved for students enrolled in the 2nd year of the current academic year)
There will be two partial written tests. The first partial test consists of two exercises on the first part of the course (mechanics) and can be taken in the winter exam session between the first and second semester (January and/or February). The second partial test, which will be concomitant to the complete tests in June and July, consists of two exercises on the second part of the course (thermodynamics and fluids). The time available to carry out each partial test is 2 hours. If the first partial test (mechanics) is passed with a mark of at least 15/32, the student is also entitled to take the partial test relating to the part of thermodynamics and fluids. If the second partial test is passed with a score of at least 15/32 and such that the arithmetic mean of the two tests is larger than or equal to 18/32, the overall written test has been passed.
During the oral exam, the teacher verifies that the student has understood the contents of the course and he/she is able to present them in a clear way. More in detail, the teacher can ask for:
- the solution of an exercise
- the analysis of a real situation that can be described using the models presented in the course
- the description of a model and of its limits of validity
- the demonstration of a physical relation
The duration of the oral exam is at the discretion of the professors.
ACCESS TO EVALUATED TESTS AND FINAL SCORE
To be able to take the oral exam, it is necessary to have obtained an access score > = 18. The access score can result from either a combination of the ongoing assessment and the final written test, or from the final written test only:
A. (reserved for students enrolled in the 2nd year in the current academic year)
The access score results from a combination of the ongoing assessments and the written test, according to an algorithm that will be described at the beginning of the course by the teachers and reported in detail on the Aulaweb page of the course. In order for the ongoing assessments to contribute to the access score to the oral exam, it is necessary to take part in a large fraction of them, that will be better quantified before the beginning of the course.. In order for the written test (1 complete, or 2 partial tests as described above) score to be valid as an access score, it must be > = 18.
B. (possible for all students)
The access score results from the written test only (1 complete or two partial tests).
An access score that is >= 18/32, obtained in mode A or B, remains valid for the entire academic year. For example, in the academic year 2022/23, the achievement of an access score > = 18/32 starting from the session of June 2023 gives the right to take the oral test in any following session, up to and including that of February 2024.
The dates of the written tests are reported on Aulaweb and on the exam calendar on the University website. Registration for the written tests through the Unige website is mandatory, students are recommended to check the deadline for registration. The oral interviews take place during each exam session, in the days following the date of the written test. The teachers communicate the date, time and place of the oral interviews at the same time or immediately after the written test.
For no reason extraordinary exam sessions will be allowed, neither written nor oral
