Physics In Galileo's timebelieved in the need for continuous action of a motor (an action on the body) so that the movement existed, an idea that persisted since Aristotle. ACTIVITY An interesting experience ... Use of an inclined plane (can be a piece of wood raised on one side) and any object (could be a marble). initially hold the positive inclination of the plane, ie upwards. Release the object. What happens to the speed of this object? And if the slope is downward, the conclusion would be the same? And if the plan is maintained with zero slope? What would be the behavior of their speed? Discuss with your colleagues. Prepare a report of the experience with their conclusions. When performing experiments with the inclined plane, Galileo found that the gravity acceleration produced in a body. This acceleration, contrary to what was thought, did not depend on speed. Concluded that under the action of a constant force, in this case the force of gravity, the space covered by a body is proportional to the square of time employed and that this body moves so that its velocity at any instant is proportional to time employee. There was a possibility of movement of a body without the continuous action of a motor? For it was what Galileo seems to have realized from their experiences. Galileo did not actually law of inertia as it is known today. In fact he lived in a world that transitioned between Aristotelian ideas and religious faith, yet so present in his time, and the new physics that seemed counter what was believed until then. But the ground was prepared for that, Issac Newton, born in the year that Galileo died, made the first great unification of Physics. This unification met terrestrial and celestial phenomena, which are now governed by the same laws. The analysis of some parts of thePrincipia may help us understand the "Institute of Mechanics". In the preface to Newton in this first edition of thePrincipia, May 1686, is the outline of what would be the new mechanics.

Fizika U Galileo vrijemevjerovao u potrebi kontinuiranog djelovanja motora (djelovanje na tijelu), tako da je pokret postojao, ideju koji se održao od Aristotela. AKTIVNOST Zanimljivo iskustvo ... Korištenje nagnutom zrakoplovu (može biti komad drveta podigao na jednoj strani) i bilo koji objekt (može biti mramor). početku držite pozitivan nagib ravnine, tj. prema gore. Pustite objekt. Što se događa na brzinu ovaj objekt? A ako je nagib prema dolje, zaključak bi bio isti? A ako je plan održava s nula padini? Što bi se ponašanje njihove brzine? Razgovarajte sa svojim kolegama. Pripremite izvješće o iskustvu sa svojim zaključcima. Prilikom izvođenja pokusa s nagnutom zrakoplovu, Galileo otkrio da je gravitacijsko ubrzanje proizvedena u tijelu. Ova ubrzanja, suprotno onome što je mislio, ne ovisi o brzini. Zaključio da pod djelovanjem konstantne sile, u ovom slučaju sila gravitacije, prostor pokriven tijela proporcionalan je kvadratu vrijeme zaposlen i da je to tijelo pomiče, tako da je njegova brzina u bilo kojem trenutku proporcionalna Vrijeme zaposlenika. Tu je mogućnost kretanja tijela bez kontinuiranog djelovanja motora?Jer to je ono što je Galileo čini se da su shvatili iz svojih iskustava. Galileo je zapravo zakon inercije, kao što je poznato danas. U stvari on je živio u svijetu koji je prenesen između Aristotelovim idejama i religijske vjere, a ipak tako prisutan u svom vremenu, a nova fizika koja činilo kontra onoga što je do tada vjerovao. No, bio je pripremio za to, Isaac Newton, rođen u godini koja Galileo je umro, napravio prvi veliki ujedinjenje fizike. To ujedinjenje sastao zemaljske i nebeske pojave, koje su sada regulirane istim zakonima. Analiza nekih dijelovaPrincipia može nam pomoći u razumijevanju "Institut za mehaniku". U predgovoru Newton u ovom prvom izdanjuPrincipia, svibanj 1686, je obris onoga što će biti nova mehanika.
