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.
How to Calculate Centripetal Force. Example 1. A small ball of mass 0.5 kg is attached to a string and it is whirled at a constant speed in a horizontal circle, which has a radius of 0.4 m. The circular motion of the ball has a frequency of 1.8 Hz. a) Find the centripetal force.
