Differentiate between gravitational constant (G) and acceleration gravity (g) ?


The difference between the gravitational constant (G) and acceleration gravity (g) are tabulated below.

Gravitational constant (G)

Acceleration gravity (g)

The Universal gravitational constant is defined as the force of attraction between two objects with unit mass separated by a unit distance at any part of this universe.

Acceleration gravity is defined as the acceleration experienced by a body under free fall due to the gravitational force of the massive body.

Universal gravitational constant is a constant value at any place in the universe.

The nature of the acceleration due to gravity varies from place to place.

The value of G = 6.673 × 10-11 Nm2/kg2

The value of acceleration due to gravity of the earth is 9.8 m/s2 and moon is equal to 1.6 m/s2.

The unit of G is Nm2/kg2

The unit of g is m/s2
