Does a person weigh more at the equator or at the north pole? How much is the difference in gravity in?

different part of the earth? Does an ounce of gold weight more at the equator or at the north pole?

1. No. Local variations in gravity due to density fluctuations in the Earth are much larger than the effect of the rotation of the Earth. NASA is mapping gravity over the Earth by satellite.
2. Actually it will weigh more at the north pole. You will also be several kilometers closer to the earth's center. This is because the earth's rotation causes it to bulge in the center. Although there are local variations, gravity rises minutely as you head from the equator to the poles. ********* See: wikipedia Earth's_gravity (Sorry, Y!A's citatitions are not currently working)
3. yes yourweight does fluctuate depending on where you are standing on the earth ...but the fluctuation is very minimal and is mostly neglected .Usually the gravitational constant for earth is taken as 9.81 m/s but which is a average value ..incase you go to the equator ...g become almost equal to 10 m/s ...and when you closer to the poles gravity slightly reduces to 9.6 m/s ....
4. There are two reasons that the gravitational field strength at the pole could be larger than strength at the equator: the rotation of the earth and the equatorial bulge (oblateness). If you run the numbers the difference is about 0.5% (978 Gal at the equator to 983 Gal at the poles). 1 Gal is 1 cm/s^2. Values for local variations that I've seen are generally around a few hundred mGal at most, less than about a tenth of the variation due to the oblateness of the earth and rotation.
