The centripetal force is a required force to maintain a velocity in constant speed as it travels in a circular path. The direction of the force is inward, toward the center of the circular path.  

The centripetal force is a required force to maintain a constant speed as the object travels in a circular path. The direction of the force is inward, toward the center of the circular path.  

The requirement of a centripetal force for such an object can be satisfied by a gravitational, electromagnetic, or any other type of force.

Where m is the mass of the rotating point mass, r is the radius is the radius of the path and omega is the angular velocity (in radians per second).
