Detailed explanation-1: -With this theory Newton reinforced the Copernican theory that places the Sun at the center of the universe. As the planets of the solar system travel at a high speed, the Sun’s greater gravitational force constantly attracts them, causing the planets to move in an elliptical orbit around the Sun.
Detailed explanation-2: -In Principia, Newton described gravity as an ever-present force, a tug that all objects exert on nearby objects. The more mass an object has, the stronger its tug. Increasing the distance between two objects weakens the attraction.
Detailed explanation-3: -Newton’s theory of gravity predicts that the gravitational force on any object is proportional to its mass, while his second law of motion predicts that the resulting acceleration is inversely proportional to the object’s mass. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003.
Detailed explanation-4: -The law of gravity and gravity itself did not exist before Isaac Newton.
