Centrifugal force is a fictitious or apparent force that is perceived when an object moves in a circular path. It is not an actual force acting on the object; rather, it arises due to the inertia of the object and the acceleration required to keep it moving in a circular trajectory. When an object moves in a circle, it experiences centripetal acceleration directed towards the center of the circle.
