Answer:
Centripetal force and Centrifugal force.
Β» similarities
β’ Both these forces act on a body moving in circular path ( circular motion )
β’ Both these forces can occur in a simple harmonic motion. ( S.H.M )
Β» differences
β’ Centripetal force acts towards the centre of circular path while centrifugal force acts away from the centre.
β’ Centripetal force is inversely proportional to radius of circular path while Centrifugal force is directly proportional to radius of the circular path.
