OVERVIEW

The course aims to provide students with a basic knowledge of classical thermodynamics and electromagnetism in vacuum.

AIMS AND CONTENT

LEARNING OUTCOMES

To provide basic knolwedge about the mechanics of a material point and of a systems of particles as well as of rigid bodies and make the student able to describe their motion in the frame of classical meccanics

AIMS AND LEARNING OUTCOMES

The course is a basis course: the learning outcomes are therefore aimed to give to the students the instruments to elaborate models of physics phenomema and to extract from those models the relationship between the physics quantities involved. The basic concepts - heat, energy, charge, electric and magnetic field and so on - are therefore defined and so are the basic physics laws governing them. Simple evolution of models in time is also studied.

TEACHING METHODS

Blackboard lessons with possible support of audio/visual material, Remote teaching if required by the safety rules.

Guided solution to exam exercises.

EXAMS

EXAM DESCRIPTION

Final examination is made of a written essay and an oral discussion on the arguments of the course.

The written essay is made of four exercises: two on mechanics, one on thermodynamics and one on electro-magnetism in the void. Students have four hours to finish the exam.

All written exams can be parted in a mechanics and a thermodynamics/electromagnetism in void part; the student can choose to build its admission with two half parts, both passed with an evaluation greater or equal to 12, and whose mean is greater or equal to 15. For each part the time for finishing it will be two hours.

No textbook or other material is allowed on the written essay - there will be a formulary downloadable from aulaweb.

Students failing the oral examination must redo also the written essay.

ASSESSMENT METHODS

The students need to be able to:

Model cyclic machines and other simple processes with regard to heat/work exchange with sources and efficiency

Model a thermodynamic process and assess the entropy variation and reversibility of it

Model electrostatic interactions between conductors/insulant object in the presence of unbalanced charge

Model simple electrical circuits with linear elements and stationary or quasi-stationary currents

Model interactions between currents and magnetic field and current-current interactions

Model electromagnetic interaction between conductive/insulant objects in quasi-stationary field flux variations
