perfície Earth. Apparently, it was suggested that the Newton gravity that makes apples fall from the apple tree and the centripetal force directed toward the Sun had the same cause: A mutual interaction that occurs between any two bodies, called gravitational force. You also may have read or heard someone speak, somewhere, that Sir Isaac Newton formulated the law of universal gravitation by observing an apple falling. Would that be possible? Or be a legend of physics? Read the text placed in sequence and draw your conclusions. A legend in the history of physics is the falling apple. Newton tried to understand why the moon did not depart from Earth in the 1660s, when standing in a garden observed an apple falling from a tree. The "story" was invented by Newton to convince and become accepted his claim that the discovery of universal gravitation occurred about 20 years before its publication in thePrincipia. This was due to a feud between him and Robert Hooke paternity of the Inverse Square Law (1 / r2), and then anticipate the discovery of universal gravitation to a period prior to an exchange of letters with Hooke. Hooke, in November 1679, wrote to Newtonpresenting you the following problem: If a body undergoes an attraction toward a center, what type of curve is its orbit, if the attraction varies inversely with the square of the distance? Newton did not respond and, in 1684, Edmund Halleyvisi-tou him and asked him the same question. Newton would have answered, that according to his calculations, was an ellipse, but found not the calculations. Halley insisted then that he wrote his calculations. The result, after some minor treatments, was the "Mathematical Principles of Natural Philosophy". With a careful reading of the book of Newton and his notebooks, LB Cohen, a scholar of Newton, proposes that: Universal Gravitation Newton arrived at by an application of his Third Law; The Third Law was not made by him in the latest draft of the Principles, around 1685. Soon the story of the apple is false, it would have happened 20 years before and; Newton learned to treat curved trajectories from a method developed by Hooke. (Adapted from DAYS; SANTOS; SOUZA, 2004, p.265-266) ACTIVITY From equation (2), what is the intensity of the force between two bodies, both bodies very small, and also separated by a small distance? Suppose, for example, mass of 1 kg and 1 m. How do you explain the fact that the bodies and the trees do not get out flying, despite the rotation of the Earth?

perfície Zemlje. Očito, to je sugerirao da je Newton gravitaciju koja čini jabuka pada sa jabukom i centripetalne sile usmjerene prema Suncu imao isti uzrok: međusobna interakcija koji se javlja između bilo koje dvije tijela, zove gravitacijska sila. Vi svibanj također pročitao ili čuo da netko govori, negdje, da je Sir Isaac Newton formulirao zakon univerzalne gravitacije promatrajući jabuku pada. Bi li to biti moguće? Ili se legenda o fizici? Pročitajte tekst stavljen u slijedu i izvući svoje zaključke. Legenda u povijesti fizike pada jabuka. Newton je pokušao shvatiti zašto Mjesec ne odstupi od Zemlje u 1660s, kada je stajao u vrtu promatrati jabuka pada sa stabla. Izbornik "Priča" je izumio Newton uvjeriti i postati prihvatio njegovu tvrdnju da je otkriće univerzalne gravitacije dogodila oko 20 godina prije objave uPrincipia. To je zbog svađa između njega i Robert Hooke očinstvo zakona obrnutog kvadrata (1 / r2), a zatim predvidjeti otkriće univerzalne gravitacije na razdoblje prije razmjenom pisama s Hooke. Hooke, u studeni 1679, napisao je NewtonPredstavljamo vam sljedeći problem: Ako je tijelo prolazi privlačnost ka centru, što tip krivulje je njegova orbita, ako je privlačnost varira obrnuto proporcionalno s kvadratom udaljenosti? Newton nije odgovorio i, u 1684, Edmund Halleyvisi-tou ga je i postavio mu isto pitanje. Newton bi odgovorio, da je, prema njegovim izračunima, bio elipsa, ali nisam našla izračuni. Halley inzistirao tada pisao svoje izračune. Rezultat, nakon nekoliko manjih tretmana, bio je "Matematički principi prirodne filozofije". Uz pažljivo čitanje knjige Newtona i njegovih bilježnica, LB Cohen, učenjak Newton, predlaže da se: univerzalne gravitacije Newton je stigao na po zahtjevu o svojem trećem Zakona; Treći zakon nije po njemu u najnovijem nacrtu načelima, oko 1685. Uskoro priča i jabuka je lažna, što bi se dogodilo prije 20 godina, a; Newton saznao za liječenje zakrivljene putanje iz metodi koju je razvio Hooke. (Preuzeto iz dana; SANTOS;. AKTIVNOST Iz jednadžbe (2), što je intenzitet sile između dva tijela, oba tijela su vrlo male, ali i odvojene male udaljenosti? Pretpostavimo, primjerice, masa 1 kg i 1 m dužine. Kako objašnjavate činjenicu da se tijela i drveće ne izađem leti, unatoč rotacije Zemlje?
