# Sir Isaac Newton

### 『By Cassandra Davis』

## 【Early Life】

From the age of about twelve until he was the age of seventeen, Newton was educated at The King's School, Grantham which taught him Latin but no mathematics. He was removed from school, and by October 1659, he was to be found at Woolsthorpe-by-Colsterworth, where his mother, widowed for a second time, attempted to make a farmer of him. Henry Stokes, master at the King's School, persuaded his mother to send him back to school so that he might complete his education.

In the year of 1661—during the month of June—he had gotten accepted Trinity College, Cambridge, on the recommendation of his uncle Rev William Ayscough. He started as a subsizar—paying his way by performing valet's duties—until he was awarded a scholarship in 1664, which guaranteed him four more years until he would get his M.A.

## 【Occupation】

Many scientist had admired his work. One of them was Edmond Halley, who was an important astronomer. Halley was the one who inspired Newton to write up his work and publish it for the world to see.

## 【Universal Law of Gravitation】

The way Sir Isaac Newton figured out the equation was by witnessing an apple fall from an apple tree. It was then Isaac though that the apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that had an effect on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity".

## 【Changing History】

The gravity formula is given by Where, G is a constant equal to 6.67 ×× 10-11 N-m2/kg2, m1 = mass of the body 1, m2 = mass of body 2, r = radius or distance between the two bodies.

This famous scientist made the world change in a good way; without understanding the force of gravity, we would have no clue why we are staying on earth and not float away into space.
