Brian,The general case I had in mind is the hollow ball bearing versus dense solid metal ball bearing.
I'm not sure what "generally" means in this case.
... The terminal velocity is directly proportional to r^2 for the series of steel balls. The data form an amazingly straight line of slope 2 on a log-log plot.

I don't think it's generally true however, that large balls drop faster in viscous liquids, though denser or heavier balls would, wouldn't they?

/snip/ The relevant drag formula in this case is Resistance = C r v, where C is a constant and r is the radius of the sphere. The terminal speed becomes proportional to r^2. /snip/
