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.
centrifugal force An effect that seems to cause an object moving in a curve to be pushed away from the curve's center. Centrifugal force is not a true force but is actually the effect of inertia, in that the moving object's natural tendency is to move in a straight line. See Note at centripetal force.
