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 radius r of this circle is equal to the mass m times the square of the velocity v divided by the centripetal force F, or r = mv2/F. The force can be calculated by simply rearranging the equation, F= mv2/r. Centripetal force is the inward-seeking pull of an object. Centrifugal force is the opposite; it appears to pull objects away from the center or axis of rotation.
