Answer:

Gravitational Field Formula

Gravitational Field FormulaThe acceleration due to gravity near the Earth depends on the distance of an object from Earth's center. The gravitational field formula can be used to find the field strength, meaning the acceleration due to gravity at any position around the Earth. The radius of the Earth is , and so values of r in the formula are (typically) greater than this radius. The gravitational field strength is measured in Newtons per kilogram (), or in the same units as acceleration, .
