How did sir Isaac newton illustrate the theory gravity?

Answer 1

Sir Isaac newton illustrated the theory of gravity through his formulation of the law of universal gravitation, which posited that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers. He famously used the analogy of an apple falling from a tree to explain how this force acts on both falling objects and celestial bodies, such as the moon orbiting the Earth. Newton’s mathematical framework allowed for predictions of gravitational effects, revolutionizing our understanding of motion and laying the groundwork for classical mechanics.
