Which is the Weakest Force in Nature

All matric students who are studying physics should be familiar with the 4 fundamental forces of nature. These four fundamental forces govern everything that happens in the universe.

Understanding the fundamental forces of nature are a large part of the physics syllabus for matric students. 9th class students who are able to firmly grasp these forces will be able to solve the past papers more effectively and score well on the final exams.

 

What are the 4 Forces of Nature?

A fundamental force of nature is an attraction or repulsion between objects as described through interactions between fields and particles. According to the study of physics, there are 4 fundamental forces of nature which together describe every action we see in the Universe, from the decay of atomic particles to the drift of entire galaxies. 

 

The 4 fundamental forces of nature are:

  1. Strong nuclear force
  2. Electromagnetic force
  3. Weak nuclear force
  4. Gravity

 

Strong Nuclear Force

The strong nuclear force is what holds together the nuclei of atoms. It is the strongest of the four fundamental forces of nature because it binds the fundamental particles of matter together to form larger particles. It holds together the quarks that make up protons and neutrons, and part of the strong force also keeps the protons and neutrons of an atom’s nucleus together.

 

Electromagnetic Force

The electromagnetic force acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force. It is long-ranged but much weaker than the strong force. 

 

Weak Nuclear Force

The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. The weak force is responsible for radioactive decay and neutrino interactions. It has a very short range and as its name suggests, it is very weak.

 

Gravity

Gravity is the attraction between two objects that have mass or energy. The gravitational force is weak but very long-ranged. Gravity is probably the most intuitive and familiar of the fundamental forces, but it’s also been one of the most challenging to explain.

 

Which is the Weakest Force in Nature?

Despite its name, the weak nuclear force is actually not the weakest force in nature. The weakest force is actually gravity. This may seem complicated, but there is a reasonable explanation for this. 

While gravity might appear to be a strong force, responsible for holding entire galaxies together and squeezing the literal daylight out of stars, it’s approximately 10^29 times weaker than the weak nuclear force. 

It is important for matric students to understand why gravity is considered to be the weakest force of nature. Since gravity has virtually no observable effect on the scale of tiny particles, it is considered relevant only on a more cosmic level.

 

How to Learn the 4 Forces of Nature

The fundamental forces are nature for all matric students to learn. It is an important part of the physics syllabus, and often appears on the final exams. Therefore, students should understand the nature, properties, and characteristics of all the forces of nature, from strongest to weakest.
