Centrifugal and centripetal force
Centrifugal force:
Consider a body tied with a string, moving with a constant velocity ‘v’ along a circular path of radius ‘r’. The magnitude of the velocity of body is constant. The acceleration of the body is known as radial acceleration or centripetal acceleration. Due to this acceleration, a force acts radially inwards, which is known as Centripetal force. The magnitude of centripetal force (Fc) is given by
Centripetal force = Fc = mv2/r
= mω2r
Centripetal force:
Newton’s third law states that action and reaction are equal and opposite. Some outward force is exerted by the body on the string. This radially outward force exerted by body on the string is known as Centrifugal force.
Centrifugal force = Fc = mv2/r
= mω2r
