Universal Law of Gravitation

  • Every particle attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them
  • Gravitational attraction between two objects
  • Inverse square law


  • $F_{gravity} = G \frac{M_1M_2}{R^2}$
    • $F_{gravity}$ is the force of gravity between two objects
    • $M_1$ and $M_2$ are the masses of two objects
    • $R$ is the separation of those objects
    • $G$ is the universal gravitational constant
