   ocr: How does a flywheel store energy? Although energy is never destroyed, it is sometimes very difficult to store in auseful form. FLYWHEEL The engine of a school bus, for example, converts chemical energy in its fuel into the kinetic energy of the moving bus. To slow down, the driver uses the brakes, which convert the kinetic energy of the bus into heat energy. It is almost impossible to convert this heat energy back into kinetic energy in the bus because the heat quickly spreads out into the air. In eftect, all of the kinetic energy of the bus is "wasted" each time it comes to a halt. Itis possi ...
