Flywheel

A flywheel is a mechanical device that stores rotational energy, functioning like a momentum reservoir. When energy is applied, it spins faster, and once spinning, it maintains momentum with minimal energy loss, releasing power steadily over time. This concept is used in engines and energy systems to smooth out fluctuations, improve efficiency, and provide consistent power output. Essentially, a flywheel helps manage energy flow smoothly by absorbing excess energy when there's too much and releasing it when there’s a shortage, stabilizing performance in various machinery and systems.
