00405 - Physics

Learning outcomes

At the end of the course, the student knows the laws of kinetmatics and classical dynamics, the meaning of work and energy, and the foundations of classical electromagnetism. 

The student is able to solve basic physics problems and to apply the acquired physics knowledge to sensors and devices relevant for modern information technology.

Course contents

-) International System of Units of Measure: Time, Mass, Length and Charge

-) Velocity and acceleration. Newton's laws of motion.

-) Work and energy. Potential energy. Conservation of mechanical energy. Dissipation of energy by viscous forces. Equivalence between work and heat.

-) Electrostatics: Coulomb's law. Electric field and potential. Gauss' theorem. Motion of charges in electric fields. Electric capacitance.

-) Electric current and Ohm's law. Mobility and resistivity: conductors and insulators. Joule effect. Electric circuits with resistors in series and in parallel. Kirchofff's laws. Capacitors in RC circuits: transient phenomena.

-) The magnetic field. Lorentz's force. Sources of magnetic field. Electromagnetic induction.  Application of electromagnetic induction.

Teaching methods

Frontal lectures using blackboard, slides, and simple in-class experiments. Each lecture is complemented by application examples and exercises. Specific sessions will be devoted entirely to exercises in preparation of the exam.

Assessment methods

A traditional written test, with 3-4 exercises including 3 or 4 questions each, covering the course program, will be used. In addition, 6-8 multiple choice question and the written answer to an open question are required to complete the written test with respect to the theoretical part. In face, the oral interview is not compulsory.

Students that pass the written examination can decide whether to confirm the obtained grade or to sustain an additional oral examination, consisting in theory-oriented questions.

Teaching tools

Available on virtuale.unibo:

-) Lecture notes 

-)  Physics problems (with solutions)
