Physics is a science that has as its object of study the universe, its evolution, its transformations and interactions in it are presented. For some reason, natural phenomena obey mathematical equations. Thus, the role of the physicist is to develop models for the phenomena expressed in mathematical equations. But be careful! These models are not nature, but the representation of it. The physical knowledge built over timeis present today in the technologies of the productive sector and our homes. Hence its importance for contemporary social practices, understanding the culture produced by men, to understand the historical relevance of this production in the history of mankind. Interestingly enough, the elegance of physical theories, the thrill of the debates on the scientific ideas, the grandeur of the physical principles, challenges all of us, teachers and students to share, albeit with a bit of mathematics, concepts and evolution of ideas in physics, present since man, by necessity or curiosity, became concerned with the study of natural phenomena. By the end of the nineteenth and beginning of the twentieth century, almost all the known physics was concentrated on the study of themovements presented in Newton'sPrincipia, Electromagnetism and Maxwell, whose synthesis expresses junction of electric and magnetic phenomena. And yet, the three laws ofthermodynamics, formulations occurred especially with the work of Mayer, Helmholtz and Gibbs, from which emerged one of the first formulations for the Conservation of Energy. Thus, the texts, which we call sheets, cover three fields of study:Motion, Thermodynamics andElectromagnetism, chosen over into the physics curriculum of high school, because theyare as unifying theories of physics. In the sixteenth century, the mecância Newton united the celestial and terrestrial phenomena, and its laws ofmotion include the Static, Dynamics and Astronomy. In the nineteenth century, the study ofthermodynamics, which had as a theme the thermal machines, unify knowledge of gases, pressure, temperature and heat. Even in the nineteenth century, Maxwell includes optics within theElectromagnetic Theory, concluding the third great systematization of Physics to join electrical phenomena with magnetic and optical.

Fizika je znanost koja ima za cilj studija svemira, njegov razvoj, njegove transformacije i interakcije u njemu su prikazani. Iz nekog razloga, prirodni fenomen koji slušaju matematičkih jednadžbi. Dakle, uloga fizičar je razviti modele za pojava izraženih u matematičkih jednadžbi. Ali budite oprezni! Ovi modeli nisu prirodu, ali zastupljenost njega. Fizički znanja izgrađena tijekom vremena danasprisutan u tehnologije proizvodnog sektora i naše domove. Stoga je njegova važnost za suvremene društvene prakse, razumijevanje kulture proizvedene od strane ljudi, razumjeti povijesnu važnost ovog proizvodnje u povijesti čovječanstva. Zanimljivo je da je elegancija fizikalne teorije, uzbuđenje rasprava o znanstvenim spoznajama, raskoš od fizičkih zakonitosti, izaziva sve nas, učitelji i učenici dijeliti, iako s malo matematike, koncepata i evolucija ideja u fizici, prisutan od čovjeka, po potrebi ili radoznalošću, postala bavi proučavanjem prirodnih fenomena. Do kraja devetnaestog i početkom dvadesetog stoljeća, gotovo svi poznati fizika je bila usredotočena na proučavanjepokreta prikazani u NewtonovePrincipia, elektromagnetizma i Maxwell, čiji je sinteza izražava spoj električnih i magnetskih pojava. A ipak, tri su zakonitermodinamike, formulacije došlo pogotovo s radom Mayer, Helmholtz i Gibbs, od kojih je jednog od prvih formulacija za očuvanje energije. Dakle, tekstovi, koju zovemo plahte, pokrivaju tri područja istraživanja:gibanja, termodinamika ielektromagnetizam, izabran preko fizike u nastavni plan i program srednje škole, jer onisu kao objediniti teorije fizike. U šesnaestom stoljeću, mecância Newton ujedinio nebeskih i zemaljskih pojava, a njeni zakonigibanja uključuju Static, dinamika i astronomije. U devetnaestom stoljeću, proučavanjetermodinamike, koja je imala kao temu toplinskih strojeva, ujedini znanje plinova, tlaka, temperature i topline. Još u devetnaestom stoljeću, Maxwell uključuje optiku unutarelektromagnetskoj teoriji, zaključivši treću veliku sistematizaciji fiziku pridružiti električne fenomene s magnetskim i optičkim.
