Centripetal Force

By Boyang Zhao

Centripetal force is the net force directed inward toward the center of a circularly moving object (the force that keeps the object moving in a circular path). The centripetal force (Fc) is given by the follow formula:

F_c=\frac{mv^2}{r}

were Fc is the centripetal force; v is the speed; r is the radius of the circular path; and m is the mass.

Centripetal force is not another type of force, but rather the net force pointing towards the center of the circular pathway. This net force is the result of the four main types of forces - tension force, normal force, and/or frictional force.
