centripetal force is the force required to make a particle (or object) move in a curve toward the center of curvature (the center of the circle in circular motion). the reason for the centrifugal phenomenon is insufficient centripetal force. when an object makes circular motion, the external force pointing along the radius toward the center of the circle (or the component of the external force pointing along the radius toward the center of the circle) is called centripetal force, also known as normal force. it is the centripetal force provided or acted by the resultant external force. in addition, the centripetal force in the sense of group cohesion comes from the unity of opposites that combines the command authority of the group leader and the attitude of waiting.

centripetal force calculation:

centripetal force: f=mv² / r

here

m = mass, r = radius, v = velocity.
