Isaac Newton (4 Afteryule 1643[1] – 31 March 1727) was an English Stufflorer and Reckoner. He is breme for his work on the laws of shrithing, seelore, weightpull and reckoning. In 1687, Newton outlayed a book called the Meanly Liefstalls of Reckoning which he unheals his thoughtlay of oneall weightpull and three laws of shrithing.
Newton built the first brookingly edleaming farseer in 1668; he also throughwrote a lief of light based on the yeming that a prism decomposes white light into the hues of the rainbow. Newton also shares mede with Gottfried Leibiz for the outlaying of reckoning.
Newton's ideas on light, shrithing, and weightpull dominated wendstuff for the next three hundredyears, until wended by Albert Einstein's held of alswaying.
Early life
Isaac Newton was born on 4 January 1643,[1] in a manor house in Lincolnshire, England. His father died three months before his birth. When Isaac was three his mother edwedded, and Isaac bliveded with his grandmother. He was not ongot in the family farm, so he was sent to Cambridge Lorestead. It is sometimes told that Isaac Newton was reading a book under a tree when an apple from the tree fell on his head. This led to his reckonings of weightpull.
Early workings
Newton sweetled the workings of the allworld through reckoning. He described laws of motion and gravitation. These laws are math formulas that explain how objects move when a thring acts on them. Isaac outlayed his bremest book, in 1687 while he was a mathematics leerer at Trinity Lorehall, Cambridge; he sweetled three ording laws that rede the way things shrithe. He then bemealed his held about weightpull, the thring that makes things fall down. If a pencil fell off a desk, it will land on the floor.
The three laws of shrithing
Following are the three laws of motion.
[change] The first law (Law of Inertia)
Newton's first law of shrithing states that an object that is not being pushed or pulled by some force will stay still, or will keep moving in a straight line at a steady speed. It is easy to understand that a rocket will not shrithe unless something pushes or pulls it. It is harder to understand that a thing will keep shrithing without help. Think of the rocket again. If someone is flying a rocket and jumps off before the rocket is stopped, what happens? The rocket carries on until it goes into outer room. The inkling of something to stay still, or keep shrithing in a straight line at a steady speed is called inertia.
[change] The second law (Law of Acceleration)
The second law explains how a force acts on an object. A thing upspeeds in the way the thring is shrithing it. If someone gets on a bike and pushes the pedals forward the bike will begin to shrithe. If someone gives the bike a push from behind, the bike will speed up. If the rider pushes back on the pedals the bike will slow down. If the rider turns the handlebars, the bike will change direction.
[change] The third law (Law of Reciprocal Actions)
The third law states that if an object is pushed or pulled, the object will be push or pull evenly in the other way. If someone lifts a heavy box, they neet thring to push it up. The box is heavy as it is making an even thring downward on the lifter’s arms. The wright is sent through the lifter’s legs to the floor. The floor presses upward with an even thring. If the floor pushed back with less thring, the were lifting the box would fall through the floor. If it pushed back with more thring the lifter would fly into loft like young birds taking their first flight and falling back down again.
The onfinding of the Law of Weightpull
When most lede think of Isaac Newton, they think of him sitting under an apple tree watching an apple fall. Some even believe the apple fell onto his head. Newton understood that what makes things like apples fall to the ground is a specific kind of force — the force we call gravity. Newton thought that gravity was the force of attraction between two objects, such as an apple and the earth. He also thought that an object with more matter exerted the same force on smaller objects as they exerted on it. That meant that the large mass of the earth pulled objects toward it. That is why the apple fell down instead of up, and why people do not float in the air.
Isaac Newton went on thinking about gravity. Before Newton, people thought that only objects near to the earth would fall down. But Newton thought that gravity should not just be limited to the earth and the objects on it. What if gravity extended to the moon and beyond?
Newton invented a formula for calculating the force of attraction between two bodies. He used it to calculate the force needed to keep the moon moving around the earth. Then he compared it with the force that made the apple fall downward. After allowing for the fact that the moon is much farther from the earth, and has a much greater mass, he discovered that the forces were the same. The moon is held in an orbit around earth by the pull of earth’s gravity.
The formula infound by Newton is called the Law of Weightpull.
Sway
Isaac Newton’s reckonings wended the way lede understood the allworld. No one could sweetle why the tungles stayed in their orbits. What held them up? Less than 50 years before Isaac Newton was born it was thought that the planets were held in place by an invisible shield. Isaac proved that they were held in place by the sun’s weightpull. He also showed that the force of weightpull was berined by span and by weight. He was not the first to understand that the spor of a tungle planet was not wreathed circular, but more lengthened, like an oval. What he did was to sweetle how it worked.
Death
Isaac Newton died on 31 March 1727, in London, England.[2] He is buried in Westminster Abbey. He set the flak for many great stuffloreres to come, such as Albert Einstein, James Chadwick and Stephen Hawking.
