Differentiate between gravitational constant( $G$ ) and acceleration due to gravity( $g$ )

Open in App

Solution

The differences between gravitational constant and acceleration due to gravity are
Gravitational constant( $G$ )
Acceleration due to gravity( $g$ )
1. The force of attraction between two bodies of unit mass separated by unit distance anywhere in the universe is termed universal gravitational constant. 1. The acceleration of a body experiencing free fall under gravitational force is termed acceleration due to gravity.
2. The value of universal gravitational constant is constant everywhere in the universe. 2. The value of acceleration due to gravity varies from place to place.
3. $G = 6.673 \times 10^{- 11} N m^{2} / k g^{2}$ 3. $g = 9.8 m / s^{2}$ on earth's surface.
4. The unit of $G$ is $N m^{2} / k g^{2}$ 4. The unit of g is $m / s^{2}$ .
