Is what I am trying to think about the fact that if you are stuck in the middle of the ocean, you may not see the effects of the tide even though it is happening?

To review, I was responding to your quote:

Not the man with the phD. Given the animated pictures he showed us the two do not differ enough considering the short amount of time the club is in contact to make that substancial a difference.

The point of my 'tide in your coffee cup' example is that the laws of force and motion apply universally. There is only one set, and there are no exceptions. So, visible or not, the 'tide' in your coffee is there; the coffee 'knows' it and responds accordingly.

Similarly, the premise that Impact lasts only a fraction of a second and that the Clubface Motion during that time cannot be readily observed, does not gain exemption from Law. Suppose the Ball was as large as the earth, the Clubface was sized accordingly and Impact lasted a thousand years. Would there then be enough difference to 'see'? Remember, regardless of magnitude or duration, the same Law applies.

The bottom line is that, however brief the moment of Impact or however slight the Clubface Motion during that violent collision, the laws of force and motion govern. The Ball knows it . . .

And tells everybody!
