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.	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.	G is a scalar quantity.
3.	It is different at different places on the surface of the earth. Its value also varies from one celestial body to another.	The ‘G’ is a universal constant, i.e., its value is the same (i.e. 6.7 x 10^-11 Nm² kg^-2 ) everywhere in the universe.
