Newton’s Law Of Universal Gravitation


Newton’s Law Of Universal Gravitation states that every particle 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 them.

$F = G \frac{m_{1}m_{2}}{r^{2}}$

, where:

  • F is magnitude of the gravitational force between the two point masses,
  • G is the gravitational constant,
  • m1 is the mass of the first point mass,
  • m2 is the mass of the second point mass,
  • r is the distance between the two point masses.

The gravitational force is inversely proportional to the square of the separation of the particles.

$F \propto \frac{1}{r^{2}}$

* Only applicable to point masses
