Newton's law of universal gravitation is a true physical law that describes gravitational the attraction between two things with mass. It is talked about in Newton's Philosophiae Naturalis Principia Mathematica. [1] The law is part of classical mechanics.

The formula is F_{g} = G \frac{m_1 m_2}{r^2}, In this equation:

  • "Fg" is the total gravitational force between the two things.
  • "G" is the gravitational constant.
  • "m1" is the mass of the first object.
  • "m2" is the mass of the second object.
  • "r" is the distance between the center of object 1 to the center of object 2.
