Perhaps there has not been a response because the questions were put too obliquely. Let me reframe the issue in a direct form and address it to the ‘centrifugal-force-is-not-real-camp’ whose members include DaveC, jumbo, Kaptain K, ljbrs, Ring, and Wiley. Do you still claim that centrifugal force is not a real force? If you answer yes, then what forces compressed the spring? If you are undecided, let us know the nature of your dilemma. Maybe we can help you resolve it.

Aw, see, I tried to stay out of this discussion because of all my previous posts on "centrifugal force," but now I've been left off Hanak's list! [img]/phpBB/images/smiles/icon_frown.gif[/img]
In your fourth experiment, instead of
spinning the contraption around your head, just lay it on your smooth floor and
pull it length-wise. The spring will be compressed by the ball's inertia, just like it did in experiment 3. It is this same "force," inertia, which compresses it in experiment 4.
I just fail to see why spinning it instead of sliding it turns the ball's "inertia" into "centrifugal force." [img]/phpBB/images/smiles/icon_smile.gif[/img]
