Centripetal force is the force pointing to the center of curvature (the center of the circle in case of circular motion) required to make a particle (or object) move in a curve. The centrifugal phenomenon is caused by insufficient centripetal force. When an object moves in a circle, the external force pointing to the center of the circle along the radius (or the component of the external force pointing to the center of the circle along the radius) 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 of the command authority of the group leader and the attitude towards the subordinates.

Centripetal force calculation:

Centripetal force: f=mv² / r

here

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