The last saturday,5th of July,Isaac Newton has published a work in three books called the Principa that states Newton's laws of motion and the most important is the law of universal gravitation that he had formulated by his own and he emodied later in his book.
Everything started when , between 1665 and 1667 Isaac Newton was sent to his house in Woolstrophe because of the Black Death , like the rest of the cambridge students.
He was sitting in the shade of a tree in deep mediation when he saw an apple fall and the concept The universal gravitation came to his mind. After this, he took years to develop it before he wrote this book. When he first presented his book to the Royal Society in 1686 Robert Hooke made a claim that Newton had obtained the inverse square law from him.
Isaac Newton exposed that
allthe objects apply a gravity force between them,wich is proportional to the product of their mass and inversely proportional to the distance between them,so he concluded this in the following formula:
