Take a view from space above the moon such that the earth was out of your field of view. You would observe the moon rotating on its axis. It's difficult to visualise from our earth bound reference point.

I agree with Adman.
And I propose that the Earth and Moon are physically linked, by gravatational forces.
And I like the comparison to the car on the roundabout too. And they are not even linked. (physically as you put it) Or would someone like to say that the car is revoving on it axis too ?
