# GENERAL PHYSICS - FIS/03 MODULE

OVERVIEW

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

## AIMS AND CONTENT

LEARNING OUTCOMES

Classical Physics Course: Newtonian Mechanics, Systems of

Inertial reference, cardinal equations, work, energy,

conservative forces. Thermodynamics: thermodynamic systems, first and

According to principle, thermal machines and yields.

Electromagnetism, in vacuum: Electrostatic conductors, currents

And magnetic field, electromagnetic induction, equations of

Maxwell in integral form

AIMS AND LEARNING OUTCOMES

Develop the critical sense of acquiring the ability to use the specific physical instruments (models, laws, theories, etc.) to observe and interpret natural phenomena and their evolution.

Essential Content:

Newton's mechanics: point mechanics laws, mechanical systems and cardinal equations, work and energy.

Thermodynamics: Energy conservation and first principle, in principle and simple applications.

Electromagnetism in the vacuum.

Learning outcomes expected:

Be able to model simple systems and solve simple problems on all topics discussed. Particular attention is paid to the estimate of the orders of magnitude and approximations with these compatible.

Teaching methods

Frontal lectures on the blackboard and slides projection.

Guided exercises and solution of exam problems.

RECOMMENDED READING/BIBLIOGRAPHY

We recommend:

W. Edward Gettys, Frederick J. Keller, Malcolm J. Skove: Classical and Modern Physics Volume 1 (Thermodynamic Wave Mechanics) Edited by McGraw-Hill

Alternatively, any University Physics Physics text that includes the parts included in the program may be used.

Aulaweb is also available on the Aulaweb's various summary transparencies of the program and a collection of exams assigned in recent years.

THE USE OF A UNIVERSITY LEVEL TEXT BOOK AND THE SOLUTION OF THE PROPOSED EXERCISES.ARE STRONGLY RECOMMENDED.

## 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 written test verifies the degree of learning by verifying the ability to work out the various parts of the program.

Usually mechanical and electromagnetic exercises are common to most of the General Physics Courses of the Polytechnic School.

The oral examination verifies the degree of knowledge and understanding of the subjects covered by the program, the ability to clearly and accurately disclose the acquired knowledge and the ability to apply such knowledge to the resolution of problems.
