There's more to inertia than Newton's First Law.

I've seen demos such as the tablecloth one described as an examples of
Newton's First Law, which is usually stated as "An object with no net
force maintains constant velocity," or words to that effect. My
problem with it is that most of these demos DO involve a net force, so
the first law doesn't hold.
