Re: [Phys-L] inertia and the tablecloth demo

[Richard Tarara <rtarara@saintmarys.edu>]

Sure, but most (if not all) of the physics we do at the introductory 
level (which is the only time that 'inertia' might be mentioned since it 
is a term some students have heard or might even have been taught in HS) 
is done in a 'lab-based' frame.   This list has drifted towards the more 
'exotic' realms over the years, but the intro course...especially for 
non-science majors...is still my main interest (even in retirement).
