Different Types of Forces

In nature, there are different types of forces. Force is defined as external energy that is applied on an object such that the state of the object from rest to motion takes place. There are four basic types of force in nature:

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

Gravitational force
Gravitational force is defined as the attractive force that exists between any two objects. Gravitational force is an example of a central force. The other examples of central forces are an electrostatic force and spring force.

According to Newton’s law of gravitation, the gravitational force is defined as the force which is directly proportional to the product of two masses and inversely proportional to the square of the distance between them. Following is the mathematical representation of it:

F = G (m1m2)/(d2)

Where,
F is the gravitational force
m1 and m2 are the masses of the two objects
d is the distance between the two masses
G is the gravitational constant

Electromagnetic force
The electromagnetic force is defined as the force that exists between the particles that are electrically charged. Following are the terms related to electromagnetic force:
● Electrons: These are the particles having a negative charge and they keep orbiting the nucleus.
● Protons: These are the particles having a positive charge.

Following are the fields that are associated with the electromagnetic force:
● Electrostatic field: This is defined as an invisible field that exists around the charged particles that are static.
● Magnetostatic field: This is defined as the field that exists when an electric charge moves at a constant rate.
● Electromagnetic field: This is defined as the field that is produced when the charged particle is accelerated.

Strong nuclear force
The strong nuclear force is also known as the strong force which binds the protons and neutrons. The particles that experience the strong force are known as quarks and gluons and the range of this force is short and that is one of the reasons why the nucleus is held so strongly in any atom.

Weak nuclear force
The weak nuclear force is responsible for radioactive decay and nuclear fusion. The weak nuclear force is also known as weak interaction and is effective only for a short-range.
