Some people may confuse centrifugal force with its counterpart, centripetal force. This is because they are closely related like the two sides of a coin. Centripetal force is the component of force acting on a body in a curvilinear motion directed toward the center of curvature. While centrifugal force is the apparent force, equal and opposite to the centripetal force, caused by the inertia of the body. Centripetal force draws a rotating body away from the center of rotation.
Centripetal force and acceleration

How is the centripetal force applied? In sports and exercise this is normally provided by some linkage, which can physically apply a force to the object of interest. Consider the case of a hammer thrower (Figure C5.3a) at the start of the movement when the hammer is increasing in speed. The force that causes the hammer to rotate around the athlete is provided through the wire. This force has two components, one acting in the direction towards the centre of rotation (the centripetal force) and the other tangential to the circular path. The centripetal force causes motion of the hammer head in a circle while the tangential force component causes its acceleration (i.e. increase in speed) around the circle. Once hammer head speed has been developed, the athlete must maintain that speed in preparation for release. Constant speed of rotation is achieved when the centripetal force alone acts (Figure C5.3b).

Centripetal force is defined as the force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation. Centripetal force is equal in magnitude to centrifugal force but in the opposite direction. FcP=-Fc=mv2r

In whirlpool, the water begins to rotate around its center and a funnel-like structure with a small cavity is formed. The surrounding objects are then spined and confined to the centre of whirlpool. Centripetal force is perpendicular to the velocity of the object. Centrifugal force acts in the opposite direction of centripetal force while maintaining a constant magnitude.
