Centripetal Force
In previous topic we have seen that the centripetal or radial acceleration is responsible for maintaining tangential direction of the velocity. The force responsible for this centripetal acceleration is called as centripetal force and it always acts towards the centre.
Centripetal force is the sum of all the real force acting towards the centre which is required to make a circular motion. Thus the resultant force acting along the radius towards the centre is called as centripetal force.

Fcp = mω2r
Fcp = mvω
Fcp = mv2/r
Centrifugal Force
Centrifugal force is the s force acting towards away from the centre of the circular path.It is a pseudo force arising due to centripetal acceleration of the frame of referenceThus the net pseudo force acting away from the radius towards the centre is called as centripetal force.
