What are the Fundamental Forces of Nature ?

There are Four Fundamental Forces of Nature.

These Four Fundamental Forces are :

  • Gravitational Force – Weakest force; but infinite range.
  • Weak Nuclear Force – Next weakest; but short range.
  • Electromagnetic Force – Stronger, with infinite range.
  • Strong Nuclear Force – Strongest; but short range.

Among these Four Fundamental Forces of Nature, the weak and strong nuclear forces are effective only over a very short range and dominate only at the level of subatomic particles. While, Gravitational and Electromagnetic force have infinite range.

There are Four Fundamental Forces of Nature. These are Gravitational force, Weak Nuclear force, Electromagnetic force and Strong Nuclear force.
Four Fundamental Forces of Nature

Gravitational Force : The gravitational force is weak but very long-ranged among Four Fundamental Forces of Nature. Furthermore, it is always attractive. It acts between any two pieces of matter in the Universe since mass is its source.

Weak Nuclear Force : The weak nuclear force is second weakest but very short ranged among Four Fundamental Forces of Nature. The weak force is responsible for radioactive decay and neutrino interactions. The weak force causes Beta-decay i.e. the conversion of a neutron into a proton, an electron and an antineutrino.

Electromagnetic Force : The electromagnetic force is weaker than the strong force but very long-ranged among Four Fundamental Forces of Nature. The electromagnetic force causes electric and magnetic effects such as the repulsion between like electrical charges or the interaction of bar magnets. It can be attractive or repulsive and acts only between pieces of matter carrying an electrical charge. Electricity, magnetism, and light are all produced by this force.

Strong Nuclear Force : The strong interaction is very strong but very short-ranged among Four Fundamental Forces of Nature. It is responsible for holding the nuclei of atoms together. The strong nuclear forces are the dominant force in reactions and it is so strong that it binds protons with like charges to the nucleus. Being strongest force in nature, it is most attractive in nature but can be repulsive sometimes. The nuclear forces have a range of 1fm.
