Gravity - Spinning = differences?

[fantastical]

If the inward-gravitational force is equal across all points on Earth, and different points on Earth spin at different rates, depending on the lattitudinal position, what are, if any, the differences between bodies with this difference of (inward gravity) - (outward spinning)?

[Hamish]

No. A force must include two componetns, a mass and an acceleration. The force keeping the body on a circular path is accelerating it as it is changing direction, this is the centipeatal force. There is no other acceleration associated with the body, therefore there is no other force acting on it.

The force pulling down is gravity.  The force responsible for reducing the masses weight is rotational velocity.   If the speed of rotation is increased sufficiently the mass weighs less and less until centrifugal force overcomes centripetal force.  Centripetal/centrifugal forces exist only as method tools, (in our minds), for the purpose of measuring the effects of actual forces, in this case gravity and inertia.

Both gravity and inertia act on objects at 'rest', (in a fixed position relative to another object).

I'm going to back the responses up a bit to one by JudgeJ, and the claim that gravity is stronger at the poles (because they are flattened). If this is inded true, and is the claim that the poles experience less rotational velocity for they cover less area over the same time as all other points on Earth, how does this discrepency reveal itself? More gravity acting on bodies at the poles, but less rotational velocity that is acting to oppose (conflicting with) this force of gravity (sic)?

That was my orginal question. Through the conceptualization of terms in responses, we could return to it. First an easy one: Are there there different forces (i.e. mechanisms, concepts, lack of better term) acting on things (bodies of various sort) at different points on Earth? Are they not so miniscule as to produce viable, apparent differences (in biological and/or physical terms)?

I just think of the great force of gravity suppressing everything at all times, and its conficting counterpart - rotational velocity. It seems to me there must be a synergistic effect of some sort. No?

I don't know why any organism would be significantly affected by what amounts to a less then 1 part in 100 difference in apparent gravity between any to points on the Earth's surface. Is this what you mean? If so does anyone know of an example of this?

[mibn2cweus]

I also thought it might be interesting to note that a balance scales measurements of weight wound not be significantly altered by either of these effects.

Thanks to all who posted. The differences do not seem to be significant ones, but interesting nonetheless ;)
