Final answer:
The gravitational constant, G, retains its value regardless of its location in the universe, i.e., 6.67×10-11 Nm2/kg2. It is the same on Earth and moon. However, the acceleration due to gravity changes depending on the mass and radius of the celestial body.
Step-by-step explanation:
The value of the universal gravitational constant, G, is same everywhere in the universe. It means the value of G on the surface of the moon would be the same as on Earth, i.e., 6.67×10-11 Nm2/kg2. The difference arises in acceleration due to gravity (g), which is 9.81 m/s² on Earth and about 1.62 m/s² on the moon, due to their different masses and radii. G, often used in Newton's equation of gravitation, is universal and doesn't change based on one's location in the universe.
