Gravitational Law, often referred to as Newton's Law of Universal Gravitation, states that every mass attracts every other mass in the universe. The strength of this attraction depends on the masses involved and the distance between them. This means that larger objects, like Earth or the Sun, exert a stronger gravitational pull than smaller objects. This law explains various phenomena, such as why apples fall from trees and why planets orbit around stars. It is fundamental to understanding the motion of celestial bodies and is a key principle in fields like astronomy and physics.
