Diffrence between centripetal and centrifugal force

Centripetal Force : In uniform uniform circular motion there is no change in magnitude of velocity, but there is only change in direction of velocity. Hence uniform circular motion is an accelerated motion.According to newton’s second law of motion, there must be a force acting on body to produce an acceleration, i.e along radius and directed towards the centre of the circle. such a force is necessary for particle to performing circular motion is called as centripetal force.
