Solution
Step1: Circular motion
Circular motion is the movement of an object while rotating along a circular path.
Circular motion can be either uniform or non-uniform.
During uniform circular motion, the angular rate of rotation and speed of the body will be constant while during non-uniform motion the rate of rotation keeps changing.
Step2: Centripetal Force
A centripetal force is that force which makes a body follow a curved path.
Its direction is always perpendicular to the motion of the body and towards the fixed.
Mathematically, , where = centripetal force, =mass, =velocity and =radius.
Thus, Centripetal force is a force that is a must for sustaining the circular motion.
