The Law of Gravity is a fundamental principle in physics that explains how objects with mass attract each other. This force is proportional to the mass of the objects and inversely proportional to the square of the distance between them. For example, the larger the mass of an object, like the Earth, the stronger its gravitational pull. Sir Isaac Newton formulated this law in the 17th century, describing it as a universal force acting between all masses. This principle helps us understand various phenomena, such as why apples fall from trees and how the Moon orbits the Earth.
