Gravity and spin
Quote:
...Now note that they have assumed that the gravitational attraction between a large body (the Earth) and a small body (a person or object on the Earth's surface) depends on the spin of the LARGE body. (Because if the Earth were not spinning, there would be no such force, according to them.)

And ask them why, in that case, the gravitational force between the small body and the large body does NOT depend on the spin of the SMALL body. (You can easily demonstrate that the time it takes a spinning object to fall is identical to the time it takes a nonspinning object to fall.)...

I suppose one could take a couple simple gyroscopes, spin one and then drop both. I wonder how far they would need to fall to see a measurable difference. I also wonder if the difference (assuming there is a difference) is related to air resistance and the wobbling of the non-spinning object. So maybe we need to change out that gyroscope for a teflon ball with a super slick surface so that air resistance falls out...

$.02 -- just thinking out loud on my keyboard over my first cup.
