Centripetal force is a force that is directed perpendicular to the velocity of an object traveling in a circular path towards the center of the circle.[1]
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.
"Centripetal" is a term derived from the Latin words centrum (meaning "center") and petere (meaning "tend towards").
The equation for centripetal force is:
<math>F = m r \omega^2</math>
Where m is the mass of the rotating point mass, r is the radius of the path and omega is the angular velocity (in radians per second).
