Difference between G and g

Here are some differences between G (the gravitational constant) and g (the acceleration due to gravity) :

Feature G (Gravitational Constant) g (Acceleration due to Gravity)
Definition G is a universal constant used in the calculation of gravitational forces between two masses. g is the acceleration objects experience when subjected to gravity on a celestial body.
Symbol G g
Value Constant, 6.67430 × 10-11 m3kg-1s-2 Varies, e.g., ~9.81 m/s2 on Earth
Unit Cubic meters per kilogram per second squared Meters per second squared
Application Used to calculate the gravitational force in universal contexts, affecting two masses anywhere in the universe. Used to define the weight of an object and how quickly it falls due to gravity on a specific celestial body’s surface.
Constancy G is constant and does not change irrespective of location or conditions. g varies depending on the celestial body’s mass and radius, as well as altitude and latitude.

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.
