No. Gravity has nothing to do with rotation. It is a fundamental force like electromagnetism and the two nuclear forces. However, because at the equator rotation produces a slight 'anti-gravity' effect making a 100 kilogram human slightly lighter by a few grams. If the Earth stopped rotating, objects would weigh exactly the same at all points on the Earth as you would calculate from only their gravitational forces alone. A 200-ton building at the equator weighs several pounds less than it would at the north pole.
