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.
This particular kind of force is called a centripetal force. The same is true for the pail of water. When you swing the pail back and forth, you can feel the pail and the water inside pulling on your arm because it wants to continue to move in a straight line and you want to make it go in a circle.
