Answer :

any motion in the curved path are accelerate motion ,and require a force which is directed towards the center of the curvature of the path is called centripetal force. its direction is always orthogonal to the velocity of the body.  
centripetal force:
A particle moving in a circle is accelerated and acceleration can be produced in an inertial frame only if a resultant force acts on it. The resultant force along the normal direction,directed towards the centre is called centripetal force.
