What is the Universal Law of Gravitation?

The Universal Law of Gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Simpler terms, means two objects universe exert gravitational force other, strength force depends masses distance them.

The Equation

The mathematical equation for the Universal Law of Gravitation is:

F = G (m1 × m2)


  • F = force gravity
  • G = gravitational constant (6.674 × 10^-11 N m² / kg²)
  • m1 m2 = masses two objects
  • r = distance centers two objects
