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 acts at right angles to an object's circular motion so the force changes the direction of the object's velocity. If the force vanishes, the object stops moving in a circular path and instead moves along the straight tangent path where the force left it.
