Relation between G and g

The relationship between G (the gravitational constant) and g (acceleration due to gravity) is expressed by the formula,

g = GM/r2

where, G is used to calculate g, using the mass M and radius r of a celestial body.

What is the Relation between G and g?

G is the gravitational constant that helps us calculate the force between two masses. On the other hand, g measures how fast objects fall due to gravity. The relation between G and g is given as g = GM/r2. In this article, we will learn about the relationship between G and g in detail.
