The Universal Law of Gravitation

The Universal Law of Gravitation states that every object with mass attracts every other object with a force that depends on both their masses and the distance between them. The greater the masses, the stronger the pull; the farther apart they are, the weaker the pull. Mathematically, this force is proportional to the product of the two masses and inversely proportional to the square of the distance separating them. This law explains why planets orbit the sun, moons orbit planets, and objects fall toward Earth, governing the fundamental interactions that shape the structure of the universe.
