Hydroelectric power plants convert the gravitational potential energy of falling water into electrical power, typically by allowing the water to flow through a pipe called a penstock to rotate a generator located below it. let the bottom of the penstock be the origin of a cartesian coordinate system and the point at which the gravitational potential energy is zero.
