How does a flywheel work?

The flywheel works based on Newton's first law of motion applied to rotating systems, wherein the flywheel keeps rotating even after removal of the source transferring rotational energy. This rotation of the flywheel after the removal of the source is then utilized to harness energy when required by the system interconnected to it.
