Question

How the value of 'g' varies with altitude?

Open in App

Solution

The value of acceleration due to gravity changes with altitude. The gravitational force above the Earth's surface is proportional to $\frac{1}{R^{2}}$ , where R is the distance from the center of the Earth. The table below shows the value of g at various locations from Earth's center:
