sense.
The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an
object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for
the acceleration due to gravity at a distance h above the surface of the Earth, g₁. Express the equation in terms of the radius R of
the Earth, g, and h.
&h=
