Don't like to be picky, Nick, but shouldn't that be "momentum"?

Inertia is what has to be overcome to move a body.  Momentum is what
has to be overcome to bring it to rest.

Admittedly it would have increased inertia when stationary.  But isn't
a moving flywheel is all about momentum?  Or have I got it all wrong?

Kind regards MMDers
