Since Pmb is playing coy I will give you my answer.

What? Since when am I playing it coy? Butchmurry asked

*Could centrifugal force affect gravity?* and I said

*Yes*. That's the best answer a person can give. If butchmurry wanted details and wanted me to elaborate all he had to do was to ask, and he did! So I will now get into the details the best I can.

Butchmurry - I appologize. I was careless in reading your answer so I got the wrong idea. Although my answer was correct, it was correct for the wrond reason. The inner bodies (yellow) a moving faster so they have a greater mass-energy. That energy increases the gravitational field in the region around the green bodies. The strength of the gravitational field is a function of the speed of the green bodies.

You were speaking about the centrifigul force, also referred to as the centrifigul field. The centrifugul field exists without the presence of any bodies and is a function only of the change in coordinates to rotating coordinates.

For details please see the article on this subject by Albert Einstein, the Master!

The article is under my web site at

**Albert Einstein** -That the relation of gravity to inertia was the motivation for general relativity is expressed in an article Einstein wrote which appeared in the February 17, 1921 issue of Nature

Can gravitation and inertia be identical? This question leads directly to the General Theory of Relativity. Is it not possible for me to regard the earth as free from rotation, if I conceive of the centrifugal force, which acts on all bodies at rest relatively to the earth, as being a "real" gravitational field of gravitation, or part of such a field?

I referred either to this part of the web page or to this exact article by Einstein before.

Any questions on the article please let me know.

I also wrote an article on Einstein's theory of gravity before. I's at
