The Four Fundamental Forces of Nature

The Four Fundamental Forces of Nature are Strong Nuclear force, Gravitational force, Weak Nuclear force and Electromagnetic force. The strong and weak forces are effective only over a very small range and dominate only at subatomic particles of the level.

 

The Four Fundamental Forces of Nature

Gravitational force and Electromagnetic force have infinite range. Let’s see them in detail.

Strengths of Fundamental Forces

  • Gravitational force is a week force but has infinite range.
  • Weak Nuclear Force is the weakest force among all but has a short-range.
  • Electromagnetic Force is a Strong force with infinite range.
  • Strong Nuclear Force is the strongest force among all of them but has a short-range.

Gravitational Force

It is a weak force, but have very long-ranged. Gravitational force is always attractive. It acts between any two parts of the matter in the world since mass is its source.

Though gravity holds stars, planets, solar systems, and galaxies together, it is the weakest of the fundamental forces, especially at the atomic and molecular scales. Relative to the other fundamental forces, Gravity has almost no effect.

Gravitational Force

Weak Nuclear Force

This force is responsible for neutrino interactions and radioactive decay. Its range is very short and very weak strength. The weak force causes Beta-decay, therefore, the conversion of a neutron into a proton, an antineutrino, and an electron. The scientist describes this force of interaction through the exchange of force-carrying particles called bosons. Specific kinds of bosons are responsible for the strong force, weak force and electromagnetic force.

Weak Nuclear Force

Electromagnetic Force

Electromagnetic force causes electric and magnetic effects such as the repulsion between two like electrical charges or the interaction of different magnets. It is high-ranged but has much weaker than the strong force. Electromagnetic attraction can be attractive or repulsive and acts only between matters that carrying an electrical charge. Light, Electricity, and magnetism are all produced by this force.

As its name shows that it consists of two parts: the electric force and the magnetic force. At first, a scientist described these forces as separate one by one, but researchers later realized that are the two components of the same force.

The electric component acts between charged particles whether they are moving or at a stationary position, creating a field by which the charges can influence each other. But once set into motion, those charged particles make to display the 2nd component, the magnetic force. The charged particles create a magnetic field around them as they move.

Electromagnetic Force

Strong Nuclear Force

Strong nuclear force interaction is very strong but has very short-ranged. It is responsible for holding the atomic nuclei together. It is basically an attractive force, but in some circumstances can be effective as a repulsive force. This strong force is carried by particles called gluons; that is, when 2 particles interact through the strong force by exchanging gluons. Thus, the quarks inside of the protons and neutrons are held together by the exchange of the strong nuclear force. It holds together quarks that makeup neutrons and protons. This strong force also keeps the neutrons and protons of an atom’s nucleus together.
