Question

Numerical problems on change in acceleration due to gravity

Answer 1

First, there is the variation of gravity with latitude that you alluded to: you weigh about 0.5% more at the poles than on the equator.

Second, gravity does indeed change with altitude.

The gravitational force above the Earth's surface is proportional to 1/R2, where R is your distance from the center of the Earth.

Answer 2

➡Acceleration due to gravity – on the earth's surface. Definition: Acceleration due to gravity of an object is its rate of change of velocity due to the sole effect of the earth's gravitational pull or gravity on that object that directs towards the centre of the earth.
