Centripetal Force


Centripetal force in a circular motion.
It is called centripetal force to force, or the component of the force acting on an object moving on a curved path, and is directed toward the center of curvature of the trajectory.

The term "centripetal" comes from the Latin words centrum, "center" and petere, "go to" and can be obtained from Newton's laws. Centripetal force always acts perpendicular to the direction of movement of the body on which it is applied. For an object that moves on a circular path with varying speed, the net force on the body can be decomposed into a perpendicular component that changes the direction of motion and one tangential speed parallel amending module speed.

The centripetal force should not be confused with centrifugal force, as explained in section Common misunderstandings.
