Knowledge and understanding
The course aims to introduce students to the fundamental concepts of classical rigid body mechanics, fluid dynamics, and special relativity.

Applying knowledge and understanding
The student should acquire methods for the solution of problems relating to the motion of rigid bodies and fluids, and special relativity.

Making judgments
At the end of the course students will be able to develop a critical approach in dealing with dynamic mechanical issues of extended bodies and of continuous media and special relativity.

communication skills
The course aims to provide students with the appropriate terminology to deal with other problems of physics of continuous media and rigid bodies and special relativity.

Learning ability
The course provides the foundation for the development of vocational training of the student.

Admission requirements

The student is supposed to be familiar with basic algebra and elementary geometry and to have attended a course on elementary physics in secondary school.

Course contents

Central field: central forces, motion in the Keplerian field, laws of the motion of the planets, study of the motion of the two bodies.

Mechanics: moment of forces; angular momentum and second cardinal equation; static equilibrium conditions; rotation and moment of inertia, Koenig theorems.

Special relativity: Lorentz transformations; quadri-intervals; relativistic dynamics; mass-energy equivalence.

Fluids: Notes on the elastic properties of bodies.
Mechanical properties of fluids. Volume and surface forces. Internal friction, viscosity, ideal fluid. Conditions of static equilibrium. Stevino Law. Pascal principle. Buoyancy. Fluid statics in non-inertial systems. Ideal fluids in movement. Eulerian and Lagrangian description. Equation of continuity. Bernoulli theorem and its applications. Laminar flow. Turbulence. Surface tension. Adhesion and cohesion forces. Capillarity.

Teaching methods

Lectures - Numerical exercises - Mentoring by older students or doctoral. The synchronous / asynchronous remote delivery of the theoretical lessons will also be guaranteed, while the exercises will be carried out in small groups and made available remotely synchronously or asynchronously. Based on the evolution of the COVID19 health emergency, the supply will also be assessed in the presence of all the activities. Mode for working students: Working students who can not attend regular classes, should contact the teacher to define the activities' of specific support. Office hours: Monday 15-17, Building Physics, office on the 4th floor or by appointment via e-mail.

Assessment methods

Written test with solution of mechanics problems of rigid bodies and motion in the central field for admission to the final oral test on the part of theory on motion in the central field, rigid bodies, restricted relativity and fluids. Any intermediate written tests. Written and oral tests could be carried out in the presence or at a distance depending on the evolution of the COVID19 situation.
