Q. Would I weigh the same at sea level as I do at higher altitudes? A. You would weigh very slightly more at sea level than at the top of a mountain, not enough for you to notice, but a measurable amount. Weight, which really means gravitational force, is proportional to the product of the masses of two objects acting on each other, in this case the giant earth and the minuscule you. If the earth were a perfect sphere, with a uniform mass throughout, and you were standing upright exactly at the surface, all the mass within the radius of the circle on which you stand would exert a gravitational force on you and contribute to your effective weight. However, distance is a factor, too. The more distance you put between yourself and the bulk of the mass of the earth, the less gravitational force it exerts on your body. By one estimate, a person who weighs 150 pounds on the surface of the earth would weigh approximately 149.92 pounds at 10,000 feet above sea level. As you get closer to the center of the earth, you would also weigh less and less, because only the mass within your radius would contribute to your effective weight. And if you were able to dig a hole to the center of the earth, your effective weight would be zero, because all the gravitational forces from every direction would be acting on you simultaneously and would cancel one another out.

Anyone know ? (150 lb. weight is at sea level)
The same I would assume, you're still inside of the Earth's gravitational pull...
Do your own homework.
150lbs, you are still in the earth's gravitational field...while not as great if you were right at the center, the difference is very very miniscule...
Yeah, but you're farther from the center of the earth (source of gravational pull)

The change in height from sea level to the top of Everest is tiny compared to the radius of the earth. Everest height: 8.85 Km. Earth Radius: ~ 6400Km.
Do the math.
you're just a fat kid arent you fatty? hey, he's just a fat kid! heres come chocolate fatso.
I think the formula would be GMearthMperson/radius but I don't know G for slugs. Mass of the person would be 150/32 sluggs. You can google the rest.
Omg ppl, if you start out at 150lbs, by the time you make it up that mountain, you are going
to lose weight because of your limited food supply and the energy it will take.

150 lb weight is at sea level where? Altitude isn't the only thing to affect your weight. You weigh less at the equator than at other latitudes because part of your weight goes to rotational acceleration (centrifugal force from the earth spinning), and the movement speed is highest at the equator where the rotational path is longest. You also weigh less when moving east than moving west, for the same reason.
I predict.......... 149.99999999999978lbs

F=ma=(GmM)/r^2 a=GM/r^2 a=[(6.673×10^-11)*(5.9742x10^24kg)]/(6378100m+8850m)^2 a=9.77268m/s^2 F=(68.039554kg)*(9.77268m/s^2) = 665.17373 newtons = 149.54 lbs
If this is for a physics class, the answer is 150 pounds. Significant digits
Originally posted by: ironwing The free air elevation correction brings the weight down to 149.58 lbs. However you have to factor in the gravity anomaly created by the mountain and the thickened lithosphere of mountain root as well as the elevation. This will add a bit to the felt weight. I used the info on page 9 of this link: //www.ees.nmt.edu/Geop/Classes/Geop308/308-Gravity-1.pdf
