Does the flywheel always spin?

So you might think a flywheel would keep spinning forever. The only trouble is, flywheels spin on bearings so, even when they’re well lubricated, the force of friction slows them down. There’s another problem too: as flywheels spin through the air, air resistance or drag slows them down as well.
