A flywheel is a mechanical device that uses the conservation of angular momentum to store rotational energy, a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant. . 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. And since the kinetic energy of a spinning object (E in the equation above) is. . Energy is stored mechanically in a flywheel as kinetic energy. Kinetic energy in a flywheel can be expressed as Ef = 1/2 I ω2(1) where Ef = flywheel kinetic energy (Nm, Joule, ft lb) I = moment of inertia (kg m2, lb ft2) ω = angular velocity ( rad /s) Moment of inertia quantifies the rotational. . flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. To oppose speed fluctuations effectively. . At the heart of a flywheel's energy storage capabilities lies the fundamental principles of physics, specifically the concepts of rotational kinetic energy and angular momentum. The following equation shows the energy of a flywheel [1]: E r o t a t i o n = I ω 2 2 where, • E r o t a t i o n is the energy stored in the rotational momentum (Joules, J) • I is the object's. .
