Question

Distinguish between centripetal and centrifugal force.

Answer 1

Hint: Centripetal Force is often confused with its center part, centrifugal Force, because they are so closely related essentially two sides of the same coin. Centripetal force directed towards inward the center of rotation, while centrifugal force acts outwardly away from the center of rotation.

Complete step-by-step answer:
Force is required to change the position of object force acts differently on objects depending on the type of motion it exhibits.
In the case of curvilinear motion, two types of force come into picture i.e. the Centrifugal Force and Centripetal Force.
The Force which requires to keep pulling the object towards the center of the circle along the radius. Due to this force only, the object moves in a circular path. If there is no Force acting on the object, it would have moved along a straight line which would be a tangent to the circle.
This force is called the centripetal Force.
You can see that even if the body moves with a constant speed, the direction of motion is changing. Since velocity is a vector quantity, it is constantly changing which means that this body is an accelerated motion.
Also we know that a Force is necessary for producing acceleration. The cause here to produce this acceleration is Centripetal Force.
If we treat the object as a reference frame, it means that you should imagine as if you are sitting inside the object. Since it's accelerating, it is a non inertial frame of reference.
We know that in any non – inertial frame, a Fictitious Force known as pseudo – force acts in it in a direction opposite to the direction of the acceleration of the non- inertial frame. Hence such a force appears to be acting in a direction away from the center of the circle along the radius. This apparent force is called the Centrifugal Force.
The Difference between them is that the former is a real force acting on the object and directed towards the center.
Whereas the pseudo force which to be acting away from the center and the object experience it.
The SI unit of Both Forces is Newton (N).

M = mass of the object
ac = centripetal Acceleration
at = Tagentine Acceleration
Fc = Centripetal Force
Fcent = Centrifugal Force

Note:
Centripetal Force, that keeps an object moving with a uniform speed along a circular path. It acts along the radius of the circle from the object towards the center. Centrifugal force acts from center to words objects.
