  Give three differences between acceleration due to gravity (g) and universal gravitational constant (G).

Answer:

                  Differences between g and G:

Acceleration due to gravity (g)	Universal gravitational constant (G)
1. Acceleration due to gravity is the acceleration acquired by a body due to the earth's gravitational pull on it.	1. Gravitational constant is numerically equal to the force of attraction between two masses of 1 kg that are separated by a distance of 1 m.
2. g is a vector quantity	2. G is a scalar quantity.
3. It is different places on the surface of the earth. Its value also varies from one celestial body to another.	3. The 'G' is a universal constant i.e., its value is the same (i.e.,) everywhere in the universe
