Value of Gravitational Constant

As the name suggests, the gravitational constant has a constant value which is used in the equation of Newton’s Law of Gravitation. In this article, we will learn about the definition and value of the gravitational constant.

What Is the Gravitational Constant?

The gravitational constant is the proportionality constant that is used in Newton’s Law of Gravitation. The force of attraction between any two unit masses separated by a unit distance is called the universal gravitational constant denoted by G measured in Nm²/kg². It is an empirical physical constant used in gravitational physics. It is also known as Newton’s Constant. The value of the gravitational constant is the same throughout the universe. The value of G is different from g, which denotes the acceleration due to gravity.

What Is the Value of Capital G?

In physics, the value of capital G (gravitational constant) was initially proposed by Isaac Newton.

The value of gravitational constant on the moon or on mars or at any part of the universe remains unchanged making it an invariant entity.
