While we often use the letter "G" to represent the gravitational constant, it's not the force itself. Instead, the gravitational force is represented by the letter "F".

Here's how the equation for gravitational force looks:

F = G * (m1 * m2) / r²

Where:

* F is the force of gravity between two objects

* G is the gravitational constant (approximately 6.674 x 10⁻¹¹ N m²/kg²)

* m1 and m2 are the masses of the two objects

* r is the distance between the centers of the two objects

So, while "G" plays a crucial role in calculating the force of gravity, it's not the force itself, but rather a constant that describes the strength of the gravitational interaction.
