Question

how does altitude affect acceleration due to gravity ?

Answer 1

The value of Gravity changes with altitude. ...the gravitational force is proportional to 1/R2 where R is your distance from the center of the Earth. Here is an example: The radius of the Earth at the equator is 5400 kilometers. Let's say you were in a jet at the equator that was 40 kilometers high above the earth's surface...thank you

Answer 2

On earth's surface ,'g' is maximum at poles and is minimum at the equator because this is the reason how altitude AFFECTS the acceleration of gravity with respect to the earth's surface.
