« on: 24/10/2010 18:19:09 »When the canon ball was in the barrel, it, the canon and the observer were in the same inertial frame. Once fired, it is no longer in that inertial frame, so although its rotational rate, in its own F of R remains the same, it appears slower when viewed from the F of R of either the observer or the canon. Right?
Nope. If you go to the flying cannonball's frame to observe how fast it spins,
you will observe that firing increased the spinning rate.
And I mean AFTER the firing you go to the flying cannonball's frame.
