Provide students with a basic knowledge of the laws of classical mechanics, electromagnetism and thermodynamics To develop the ability to solve simple physical problems and experiments. To provide students with the methodology required to analyse and process experimental data.
Educational objectives are focused on learning the basics and analytical description of mechanical, thermodynamic, and electromagnetic phenomena, and methods for defining quantitave relationships between observations of natural facts and their models. For this, emphasis is placed on observing natural facts, defining and quantifying the quantities involved, and relating them to models that describe why phenomena occur and how they occur. The objectives of physics teaching are supplemented with practical laboratory of general physics, where the steps of observing and quantifying phenomena through measuring instruments are more developed. The expected outcomes are: observation skills, quantification of physical quantities, analytical modeling and prediction of natural facts in the areas of mechanics, thermodynamics and electromagnetism.
Teaching is performed with classroom lectures and exercises on the topics of the program. Experimental classroom demonstrations will take place to support the theoretical lectures according to the availability and possibilities of teaching aids. The recommended texts are the basic reference for study and exercises. Topics covered in the lectures will be posted as notes on the aulaweb site. Laboratory activities will be preceded by a lecture in which the objectives, methods and technical details are described. Tracks for conducting the experiments will be posted on Aulaweb. The experiment concludes with the completion of a form in which the following should be reported: the measurement methodology, the data acquired in the form of tables and graphs, and the result of the measurement with estimated uncertainties.
Teaching program is divided into Mechanics, Thermodynamics, Electromagnetism and Physics Laboratory.
Mechanics.
Motions and Forces: velocity, acceleration, mass, forces, main types of motion, reference systems and Newton's laws, force fields, force of universal gravitation, motions of planets. Work and Energy: mechanical work, potential and kinetic energy. Law of conservation of mechanical energy and conservative forces. Dynamics of systems: center of mass, momentum, angular momentum, torque, conservation of momentum and angular momentum. Notes on mechanics of rigid and fluid and elastic solids: moment of inertia, shock, rotational energy, internal energy, hydrostatics and fluid motion, regimes of motion, law of conservation of energy, viscous fluids.
Thermodynamics.
Miscroscopic representation of hydrostatic systems: kinetic theory of ideal gases, pressure, internal energy, temperature. Heat and generalization of conservation of energy, first priciple of thermodynamics. Thermal machines, Carnot cycle, absolute temperature, second principle of thermodynamics, entropy.
Electromagnetism
Electrostatics: electric charge and electrostatic force, electrostatic field, potential, capacitance, dielectrics. Electromotive force, electric currents, resistance, circuits and circuit laws, RC circuit. Magnetostatics: magnetic forces, magnetic field and electric currents, induced electromotive force, inductance, diamagnetism and paramagnetism, ferromagnetism, magnetic properties of matter. RL circuits. Maxwell's equations, electromagnetic waves and light.
Physics Laboratory.
The experimental method in the natural sciences: scientific method; experimental observations and theories; experiment and measurements. The concept of measurement: measurable quantities; units of measurement; measuring instruments; general types and behaviors of measuring instruments. Quality of measurements: value and uncertainty; reproducibility and repeatability. Analysis of uncertainties in measurements: systematic and random; statistical treatment; functions of physical quantities with affected by uncertainty; determination of a law from experimental data. Laboratory Activities: six small experiments selected to place the student in the condition of the experimenter who, in the complexities of phenomena, must use instruments correctly to make a measurement, or several measurements, in order to describe a phenomenon quantitatively and associate an uncertainty and communicate the final result.

From September 25, 2023
Written test on Physics teaching topics and written quiz exam on Laboratory topics. Written in-itinerary tests on mechanics, thermodynamics and electromagnetism will be given during teaching, which can be valued in the exam.
Assessment of the degree of knowledge of the physics concepts described in the Syllabus, the ability to interpret a phenomenon, construct the explanatory model and use it for quantitative prediction of the physical quantities that are involved. Assessment of the ability to observe phenomena in detail, make measurements and estimate uncertainties.
