Final answer:
6.673 x 10^-11 N m^2/kg^2 referred to in the question is the Gravitational Constant. It's widely used in physics, specifically in Newton's Law of Universal Gravitation which governs the gravitational force between two masses.
Step-by-step explanation:
The number 6.673 x 10-11 N m²/kg² is a universal constant in Physics known as the Gravitational Constant or G. It is used in the formula for calculating gravitational forces between two masses. This mathematical equation is known as Newton's Law of Universal Gravitation. In the formula, G stands for the gravitational constant, m₁ and m₂ are the masses of two bodies, and r is the distance between the centers of the two masses. The formula is expressed as F = G * (m₁*m₂)/ r². Here F stands for force, illustrating the strength of gravity between two objects.
