First, we understand the basic definition of centrifugal force- The force which acts on an object rotating in a circular path away from its axis of rotation, the force acts on the outward direction is known as Centrifugal Force.
F= mѠ2r
Where, F = Centrifugal force acting on an object
m = Mass of the object
Ѡ = angular velocity of an object
r = radius of an object rotating at a distance from the axis of rotation
We go through many scientific applications in our daily routine, but we don’t know its working principle. Centrifugal force is one of the common forces that we experience in our daily life. So, in this article, we discuss some basic practical applications of centrifugal force.
- Turning of cars and buses at corners
When vehicles used to take a turn at corners the unseen force experienced by the passenger. Due to this force, the passenger pulled towards the edge of a vehicle. This unknown force is a centrifugal force.
- Drying clothes in Washing Machine
We all have a washing machine at home and we used to dry our wet clothes in it. But we ever thought about how it dries our wet clothes without any exposure to sunlight.
When we put wet clothes in the machine, it rotates in a circular path at high RPM (revolutions per minute) with the help of an electric motor. Due to this a force is applied to clothes in an outward direction, which pulls the water molecules from clothes. As a result, we get dried clothes. So, this is the principle of centrifugal force behind this.
- Rotating Bucket full of water
When we see someone doing a trick with a bucket full of water and rotate it without falling any single drop of water. Our reaction always is “Woah” – But, we ever think how does this happen?
Basically, when we rotate a bucket filled with water at a vertical axis at some speed. Then the opposite/outward force acts on the water which is equal to the weight of water. Due to which water stays inside the bucket. And the force which act in the outward direction is known as centrifugal force.
- Centrifuge machine
Centrifuge machine basically works on a centrifugal force. In this, a liquid material such as milk is placed in a tube and used to rotate it at a very high RPM (revolutions per minute) in a horizontal path. This leads to acting pressure inside the tube which results in pulling solid suspended particles (cream) from milk. And, As a result, we get solid particles (cream) from milk.
This application is mostly used by dairy farmers, dairy companies, food labs and medical labs (for separation of blood) etc.
