Why does a flywheel rotate?
Why does a flywheel rotate? A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. What is a rotating flywheel? A flywheel is a spinning wheel, or disc, or rotor, rotating around its symmetry axis. Energy is stored as kinetic energy, more specifically rotational energy, of the rotor: where: is the stored kinetic energy, ω is the angular velocity, and. How does your...
