It is harder to understand that an object will continue to move without help. It is easy to understand that a rocket will not move unless something pushes or pulls it. Newton's first law of motion states is 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. This led him to enter the field of physics, where he prospered. In his book Isaac also used his laws to show that the planets revolve around the suns in orbits that are oval, not round. If a pencil fell off a desk, it will land on the floor, not the ceiling. Gravity is the force that causes things to fall down. He then described his idea, or theory, about gravity. In the Principia, Isaac explained three basic laws that govern the way objects move. Isaac published his most famous book, Principia, in 1687 while he was a mathematics professor at Trinity College, Cambridge. These laws are math formulas that explain how objects move when a force acts on them. He described laws of motion and gravitation. Newton explained the workings of the universe through mathematics. This led to his calculations of gravitation. It is sometimes told that Isaac Newton was reading a book under a tree when an apple from the tree fell next to him. In June 1661, he was sent to the University of Cambridge to study. Henry Stokes, master at The King's School, requested his mother to send him back to school. His mother tried to make him a farmer, but he did not like that. When he was seventeen, he was removed from school. Young Newton remained with his maternal grandmother, Margery Ayscough.įrom 1655 to 1659, Newton was educated at The King's School, Grantham. When Newton was three, his mother, Hannah Ayscough, remarried with Reverend Barnabas Smith.
His father, also named Isaac Newton, died three months before his birth. 4 January 1643) "an hour or two after midnight", at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire, England.
Isaac Newton was born (according to the Julian calendar, in use in England at the time) on Christmas Day, 25 December 1642 ( N.S. The discovery of the Law of Gravitation.
