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.
Sometimes people mistakenly say 'centrifugal force' when they mean 'centripetal force.' The velocity of the object is constant and perpendicular to a line running from the object to the center of the circle; it is called tangential velocity.
