How does acceleration due to gravity vary with height?

Answer 1

The steeper the gradient (height) the greater the increase of acceleration will be.

For example; if you are riding a bike down a steep hill the acceleration will be greater than when you are riding a bike along a horizontal stretch of land.

The more distant the object is from the earth the less acceleration it has if let to fall (the rate 9.8 refers to the height nearest the surface of the earth).

Are you kidding me ? you couldn't be more wrong ?! please don't talk about things you clearly don't know about. Even though your velocity increases the acceleration due to gravity will remain the same if you anywhere near the earths surface.

i believe the formula you are looking for is

g=g(o)(r/(r+h))^2

Where g(o) is the gravity of earth

r is the radius of earth

an h is the height you are from it

You can we u have to be a considerable distance in order for things to change however the further you get out the value of g drops rapidly due to the inverse square law

Answer 2

The higher you are, the farther away you are from the center of the earth. (Where gravity pulls us towards.) So if you were carrying a bag 1,000 pounds of gold and 1,000 pieces, (each piece is one pound) to the top of a mountain it may way 999 pounds but with 1,000 pieces of gold still. Kind of like pressure in the atmoshere, the lower you are, the more air is above you so there is more pressure. And the exact opposite when you are higher up.

Answer 3

-- It depends on the masses of both bodies involved ... or on only the bigger one

if it's much bigger than the smaller one, like for example a planet and a stone.

-- It also depends on the distance between the centers of mass of the two bodies

involved.

Answer 4

Because the earth is not a perfect circle or perfect sphere. So at the poles, the force of gravity is ls different from that from the center of the earth.
