Four Fundamental Forces
In Nature
There are four fundamental forces in nature that govern the diverse phenomena
of the macroscopic and microscopic world. These different type of forces are:
- Gravitational force
- Electromagnetic force
- Strong nuclear force
- Weak nuclear force
The unification of different forces/domains in nature
is a basic quest in physics, the gravitational force is the force of mutual
attraction between any two object’s by virtue of their masses. It is a
universal force. The electromagnetic force is the force between charged
particles. The strong nuclear force is the force between protons and neutrons.
The weak nuclear force appears only in certain nuclear processes such as beta-decay
of nucleus.
