We consider wastewater treatment as a water use because it is so interconnected with the other uses of water.
Definition of Centripetal Force. Centripetal force is a force that makes an object follow a curved path. The direction of the force is oriented at a right angle to the direction of travel of the object, toward the center of the circle along which the object is moving.
Centripetal force counteracts centrifugal force, which is not a real force but is the tendency for objects on a circular path to leave the path in a straight line. Finally, tangential velocity is the constant velocity of the object that is perpendicular to the line running from the object to the center of the path.
