Sir Isaac Newton -- The Discoverer of Gravity! Newton also realized that the moon would fly off away from Earth in a straight line tangent to its orbit if some force was not causing it to fall toward the Earth. The moon is only a projectile circling around the Earth under the attraction of Gravity.What did Isaac Newton discover other then gravity?
Besides his work on universal gravitation (gravity), Newton developed the three laws of motion which form the basic principles of modern physics. His discovery of calculus led the way to more powerful methods of solving mathematical problems. His work in optics included the study of white light and the discovery of the color spectrum.How did Isaac Newton prove gravity?
Newton's major goal was to explain planetary motion. As mentioned earlier, Johannes Kepler had devised three laws of planetary motion without the use of Newton's law of gravity. They are, it turns out, fully consistent and, in fact, one can prove all of Kepler's Laws by applying Newton's theory of universal gravitation.How did Sir Isaac Newton found out about gravity?
The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.
