Newton and his three laws Isaac Newton's story of how an apple falling from a tree and hitting his head inspired him to formulate a theory of gravitation is one of those that all school-age children grow up hearing about. Newton is undoubtedly one of the most influential scientific minds in human history. He published books such as Arithmetica Universalis, The Chronology of Ancient Kingdoms, Methods of Fluxions, Opticks, the Queries and, most famously, Philosophiæ Naturalis Principia Mathematica. He formulated the three laws of gravitation, discovered the generalized binomial theorem, developed calculus (sharing credit with Gottfried Wilhelm Von Leibniz, who developed the theory independently), and worked extensively on optics and the refraction of light. Newton changed the way people looked at the world they lived in and the way the universe worked. Sir Isaac Newton was born on Christmas Day, 25 December 1642 according to the Julian calendar (4 January 1643, Gregorian calendar) at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, three months after his father's death. He was born prematurely and his mother Hannah Ayscough reportedly said he was small enough to fit in a one-liter cup. Newton's mother remarried when he was three and left him in the care of his grandmother. This incident created a great emotional distance between the scientist and his mother and, in addition to this, Newton also confessed that he had frightened his parents by threatening to burn them and their house. Another sad aspect of Newton's personal life is that, although he was engaged, he never married. Newton studied at King's School in Grantham from the age of twelve to seventeen, where he learned only Latin and no mathematics. His mother re...... middle of paper ...... each individual considers the earth as a particle to do the analysis based on its orbital motion around a star. Here mass, acceleration, momentum and force are the quantities that are externally defined, i.e. they are the externally defined quantities. It is equally true that Newton's laws of motion are not sufficient to characterize the motion of deformable and rigid bodies. After the generalization of the laws of motion proposed by Newton in 1950 by Leonhard Euler, the laws were equally accepted for rigid bodies, and these were later called Euler's laws of motion. This theory was later applied to deformable bodies, and the laws were equally true in that condition as well. Although this law is overridden by the laws of relativity, this law is equally applicable in the situation where the speed of objects is less than the speed at which light travels.
