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.
The centrifugal force is an outward force apparent in a rotating reference frame; it does not exist when measurements are made in an inertial frame of reference. All measurements of position and velocity must be made relative to some frame of reference.
