Would I weigh the same at sea level as I do at higher altitudes?

Answer 1

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..

Answer 2

No. According to the Universal Law of Gravitation ,

Weight=mg
where,
m=Mass of a body
g=Acceleration due to Gravity.


Again, g=G M / (R+h) (R+h)

Here, G is the Gravitational Constant,
M= Mass of the Earth
R=Radius of the Earth
h=Height

As h increases ,the value of g increases, thereby,the Weight. So, as height increases from the sea level to higher altitude there must be an increase in the weight of your body though, it's negligible.

Answer 3

Remember the strength of gravity is the mass of the two bodies divided by the square of the distance between the .
as your altitude increased you would weigh less.

Answer 4

One of the things that determines the strength of gravity is how far you are from the center of that gravity -- the closer you are to it the stronger is gravity. Earth's gravity center is near its physical center, so the farther away from there you are gravity weakens. Actually the top of your head experiences slightly less gravity than your feet..!

Answer 5

no. i think.. i just cant remember the term.. because what i remember was that it work like gravity.. you know, like you weigh one sixth than you are at sea level than when you are on the moon??

Answer 6

Yes because you are still in the same atmosphere which means same gravatational pull. So if you were in an airplane at 35,000 feet, and weighed 120 pounds on the ground, it would stay the same.

Answer 7

Definitely not since the value of accelaration due to gravity(9.8)keeps changing with height though slightly.
