ocr: Water and energy When water flows out ofa tap ithas kinetic energy (energy of motion). When a tap 1s off, energyis stored in water that 1S trappedin the pipes leading to it. Energy that is stored is called potential energy- When you open a tap, this trapped water 1S set free. Iti flows downward through the outet of the tap, converting its potential energy into kinetic energy. The greater and faster the flow of water, the greater the kinetic energy the water has.
