Newton's law of universal gravitation - Statement

Newton’s law of gravitation states that every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

State And Explain Newton’S Law Of Universal Gravitation?

The mathematical representation of Newton’s law of gravitation is:

\(\begin{array}{l}F=-G\frac{m_{1}m_{2}}{r^{2}}\end{array} \)


  • F is the force acting between the particles
  • G is the gravitational constant
  • m1 and m2 are the mass of the particles
  • r is the distance between the particles

The SI unit of gravitational constant is

The CGS unit of gravitational constant is dyne.cm2g-2.

The dimensional formula of the gravitational constant is [M-1L3T-2].
