Sir Isaac Newton was a great scientist in mathematics and astronomy. It is Newton who discovered the force of gravity which resulted in the Universal Law Of Gravity. Newton was born on January 4, 1643 in the manor house of Woolsthorpe, near Grantham in
Lincolnshire, England. His father died 3 months before Newton’s birth. His father was wealthy farmer who owned land and animals but he was not educated. Hannah Ayscough(Newton’s mother)remarried Barnabas Smith, church minister. His stepfather did not accept him. His mother moved to North Withham, Where she had three more children. Newton was left with his grandparents in Woolsthorpe. He did not have happy childhood because he was treated like an orphan.
Reverend Smith died when Newton was ten years old. His mother moved back to Woolshtorpe with the three children. Newton went to a grammar school at the age of 12. When he turned 17, his mother called him to help run the farm. He did not enjoy the work and did not do well. Newton went back to the Free Grammar school to complete his school educate on June 5, 1661. He entered Trinity College at Cambridge University while studying at Cambridge, he showed interested in math. He received his bachelor’s degree in April 1665. He went home in the summer of 1665 because the plague closed the university. It was at this time (Newton was still under 25 years old) that his scientific genius started to show. He began revolutionary advances in mathematics, optics, physics, and astronomy while he was studying and doing research at home.
Newton returned to Cambridge in 1667 and received a fellowship at the college of the Holy and Undivided Trinity which allowed him to continue the studies he had begun. He stared at the Trinity for 22 years. In 1689 Newton was elected a member of Parlia for the university and he moved to London. In 1696 Newton was appointed Warden of the London Mint and became master in 1699. His duties were to revise the British Coinage and Preventing counterfeit coins. He died on March 31, 1727 at the age of 84.
One of Newton’s greatest accomplishments is in the study of Physics. He was the first to scientifically describe the nature of gravity. Gravity is the force that holds us to the ground. It governs motion throughout the universe and keeps the moon in orbit around the Earth and the Earth in orbit around the sun. Newton established that all objects regardless of size have gravity. He noted that small objects have less gravity than large objects and that the force of attraction diminishes rapidly as the objects move apart. Newton researched to the Universal Law Of Gravitation. The force of gravity was discovered as a fundamental force of nature. Gravity acts on all matter and its effect are felt through out to universe. Gravity holds together planets and stars, organizes solar systems and galaxies; it orders the universe. Newton’s Law of Gravity states that any piece of matter will feel gravity; gravity depends on only the masses of the two attracting objects and their distance from each other not their chemical composition or density; and it is always attractive, never repulsive.
One of the importances of Newton’s Law of Gravity is the possibility of space travel and study. It gives us a scientific understanding of our Earth and universe. Other importance is that it led to further studies of other forces observed. In nature like tensions, spring forces, viscosity, friction, electricity, magnetism, heat, light and chemical actions. The discoveries of these forces were important in how they could be used in the industrialized.
