SUMMARY

The acceleration due to gravity at a distance of one Earth radius above Earth's surface is calculated using the gravitational force equation. By equating gravitational force to mass times acceleration (F = ma), the mass cancels out, leading to the conclusion that gravity decreases with distance from the Earth's center. Specifically, at one Earth radius above the surface, the acceleration due to gravity is one-fourth of its value at the surface, which is approximately 9.81 m/s², resulting in a value of about 2.45 m/s².

Use the expression for the gravitational force, then equate that force to [tex]ma[/tex], there being an m in your expression for the gravitational force, the "m"s would divide out.
