How did Newton arrive at the conclusion that the force of gravity is directly proportional to the product of the masses of two objects, and inversely proportional to the square of their distance?
I know that he was the first to realize it's gravity that keeps the planets in orbit, but what observations enabled him to formulate his law of universal gravitation?
Did he figure out circular motion after he formulated his three laws of motion?
