Centripetal force (centripetal force) is the force required to point a particle (or object) toward the center of curvature when moving in a curve (that is, the center of a circle when moving in a circle). The cause of the Centripetal force is insufficient. When an object moves in a circle, the external force pointing toward the center of the circle along the radius (or the external force pointing toward the center of the radius) is called Centripetal force, also known as the normal force. Is provided by external forces or acts as a Centripetal force. In addition, Centripetal force in the sense of group cohesion comes from the combination of group leadership, command authority and attitude.
