Does the earth's rotation affect the force of gravity Near the equator?

Does the earth's centrifugal force from rotation cause people Closer To the equator to experience slightly less gravity than people closer to the poles?

Does it affect the actual force of gravity? No (except to the extent that it distorts the shape of the Earth). Does it affect the *perceived* gravity (the measurable acceleration towards the center of the Earth)? Yes. 

How much? The equatorial velocity of the Earth's rotation is 465.1 m/s. The equatorial radius is 6378.1 km. Therefore the centripetal acceleration required to maintain the uniform circular motion of objects around the equator is a = v^2 / &rho;  = (465.1)^2 / (6378100) =  0.034 m/s^2 . Subtract that from the standard gravity *g* and you get *g**_net_* = 9.77265 m/s^2 . This is about a 0.35% difference.
