Physics Why had the ball this property? Stephen Gray(1666-1736) realized that it was possible to carry the electricity through wires. Depending on the material of this yarn, the conduction was better or worse, reaching in some cases behaving as an insulator (not carried electricity). From the idea of electrical conduction, Charles Du Fay(1698-1739), proposed that there were two kinds of electricity, because while some materials are attracted after rubbed with cloth, repelled others. Those who behave like glass associated with vitreous electricity, those who behaved like resin, partnered with resinous electricity. Later Benjamin Franklin(1707-1790) defined as positive and negative vitreous to resinous, and that's how we call yet. He advocated the idea that electricity consists of only one type of fluid. It was the idea of "single fluid", which appeared at first in 1747. All non-electrified body has a natural amount of fluid. This quantity is proportional to the size of the body. A body that possess excess fluid was called by Franklin "positive", and had it fail (always in relation to the natural amount), was called "negative." It is possible that the idea of conservation loads have origins in the theories of electric fluid. ACTIVITY Choose some materials like silk, party balloons, straws and paper towel. Check what happens when you rub the paper towel filled with balloons. The balloons attract? Repe- lem is? If instead of balloons you use straws? Notice any similarity or is completely different? Adopting the same procedure, but making use of silk instead of paper towel, repeat the experiment and compare the results now, with those of the first experiment. the balloons arthritis in his colleague's hair, what happened? Why? So if you watched the text here, what kind of electricity could associate with these materials? Discuss with your colleagues! Observing the behavior of bodies when electrified,it was noticed that some are attracted or repelled with greater or lesser intensity. Thus, a concern was to measure the intensity of the force with which the electrified bodies were attracted or repelled, and further that such agents would be responsible for strength and its variations.

Fizika Zašto je loptu ovaj objekt? Stephen Gray(1666-1736) shvatio je da je moguće da nose struju preko žice. Ovisno o materijalu od ovog pređe, Provedba je bolje ili lošije, dosegnuvši u nekim slučajevima ponaša kao izolator (ne provodi struju). Od ideje električnu vodljivost, Charles Du Fay(1698-1739), predložila da postoje dvije vrste struje, jer dok su neki materijali privukla nakon gumiran s krpom, drugi odbija. Oni koji se ponašaju poput stakla povezane s staklastog električne energije, one koji su se ponašale poput smole, udružio s smole struje. Kasnije Benjamin Franklin(1707-1790) definiran kao pozitivne i negativne staklastog do smolaste, a to je kako mi zovemo još. On je zagovarao ideju da se struja sastoji od samo jedne vrste tekućine. To je ideja o "jednom tekućine", koji se pojavio na prvom mjestu u 1747. Sve ne-naelektriziran tijelo ima prirodni količinu tekućine. Ova količina je proporcionalna veličini tijela. Tijelo koje posjeduju višak tekućine je pozvao Franklin "pozitivno", a to je ne (uvijek u odnosu na prirodnu iznosa), zvao "negativna". Moguće je da je ideja o očuvanju opterećenja imaju korijene u teorijama električne tekućine. AKTIVNOST Odaberi neke materijale poput svile, stranačkih balona, slamke i papirnatim ručnikom. Provjerite što se događa kad se utrljati taj papir ispunjen balonima. Baloni privući? Repe-lem Ako se umjesto balona možete koristiti slamke? Obavijest bilo sličnost ili je potpuno drugačija? Usvajanje isti postupak, ali uz korištenje svile umjesto papirnatim ručnikom, ponoviti eksperiment i usporediti rezultate danas, sa onima od prvog pokusa. Baloni artritisa u njegov kolega kose, što se dogodilo? Zašto? Dakle, ako ste gledali tekst ovdje, kakav električne energije mogao povezati s tim materijalima? Razgovarajte sa svojim kolegama! Promatrajući ponašanje tijela kada je elektrificirana,primijećeno je da su neki privlači ili odbija s manjim ili većim intenzitetom. Dakle, problem je izmjeriti intenzitet sile s kojom je nabijeni su tijela privlači ili odbija, te da takvi agenti će biti odgovoran za snagu i njegove varijacije.
