Centrifugal force is an apparent force that acts outward on an object moving in a circular path. It is not a real force but rather a result of inertia, which is the tendency of an object to resist changes in its motion. When an object moves in a circle, it feels as if it is being pushed away from the center of the circle. This effect can be observed in everyday situations, such as when a car turns sharply. The passengers inside may feel as if they are being pushed against the door, which is a result of inertia and the circular motion of the vehicle.
