When energy is applied to the flywheel, it spins, converting electrical energy or other forms of energy into rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . It follows on from these basic laws of physics that a flywheel will store more energy if it has either a higher moment of inertia (more mass or mass positioned further from its center) or if it spins at a higher speed. This technology is gaining traction for its durability, rapid response times, and eco-friendly profile. This is similar to how a potter's wheel or a spinning top holds energy while in motion.
