Which is the weakest force in nature ?

The weakest force in nature is the Gravitational force.

In nature, there are four universal or fundamental forces. These forces are:

  • Electromagnetic force.
  • Strong nuclear force. (strongest force)
  • Weak nuclear force.
  • Gravitational force. (Weakest force in nature)
Gravitational Force is the weakest force in Nature. However, it is very long ranged force. This gravitational force is always attractive in nature.

Important Facts about Gravitational Force :

  • The gravitational force is weak but very long-ranged among Four Fundamental Forces of Nature.
  • The gravitational force is always attractive despite being weakest force in nature.
  • It acts between any two pieces of matter in the Universe since mass is its source.
  • Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.
  • The value of the gravitational constant (6.67 x 10-11) is very small. Therefore, the value of the gravitational force also becomes small. This makes the gravitational force the weakest force.
