Newton's Law of Universal Gravitation

Newton's Law of Universal Gravitation states that every object with mass attracts every other object with a force that's directly proportional to their masses and inversely proportional to the square of the distance between them. This means larger objects exert a stronger gravitational pull, and the pull weakens quickly as the distance increases. For example, Earth pulls objects toward it, keeping us grounded, while the Sun's much larger mass influences planets to orbit around it. This universal attraction explains why objects fall, why planets orbit stars, and how galaxies stay together.
