if you know the acceleration due to gravity at earth surface (g) , and want to know new value higher up, you can use this:
a= g/((d/r)^2)
a = new acceleration value (m/s)/s
g = 9.81 (m/s)/s (surface acceleration)
d = new distance from earth center
r = distance to surface from earth center
: say you wanted to know the acceleration at geo stationary orbit (which is earth radius(6 371 000 meters) + 35 786 000 meters = 42 157 000 meters
from earths center, then
a= 9.81/((42 157 000/6 371 000)^2
a= 9.81/43.785
a=0.224 (m/s)s

What is geopotential altitude?
It is a correction/adjustment to Geometric Altitude using variation of gravity with latitude and elevation and hence it is also known as ‘Gravity Adjusted Height’.
When a geologist monitors a fault what kinds of data do they collect?
they collect changes in elevation tilting of land surface and ground movements
What is the elevation when you are at sea level?
The simple answer is zero feet elevation, but first of all, it is almost impossible to tell that you are at the exact sea level that is the average of all the different sea levels caused by all the different tide elevations. That is why GPS and surveying do not much use "mean sea level", anymore. These days "zero elevation" is determined by the strength of the field of gravity as calculated and measured all around the world.
What is actual pressure?
(meteorology) The atmospheric pressure at the level of the barometer (elevation of ivory point), as obtained from the observed reading after applying the necessary corrections for temperature, gravity, and instrumental errors. Source: Answers.com
Why is elevation importance?
Why is elevation important

What is the relationship of elevation gravity and weight?
weight and gravity is both in the section of masses.
Is elevation interval data or ratio?
interval
What is the Taiga elevation?
The evevation is like earths axis tilted and there is a lot of gravity.
Removing errors in data input is also referred to as?
data correction.. it works like Sudoku.. it a mathematical equation..
Which are the characteristics of statistical time division multiplexing?
error correction data compression
Does gravity have a play in the river flow?
Yes - water flows from a higher elevation to a lower elevation. That's why a lot of rivers flow from South to North

How does elevation affect drainage?
A river naturally flows from high to low elevations by gravity.
What layer of the OSI model defines how data is formatted for transmission and typically includes error detection and correction to ensure reliable delivery of the data?
Data Link
