Question

Differentiate between $g$and $\mathrm{G}$.

Answer 1

The difference between $g$and $G$ is,

Acceleration due to gravity $g$	Universal Gravitational Constant $G$
1.The acceleration that a body acquires due to the gravitational force of attraction is called acceleration due to gravity.	1.The gravitational force between two bodies of unit mass separated by a unit distance is called the universal gravitational constant
2. The value of $g$ is not a universal constant. Its value is different for different planets as the mass of planets differs. Its value decreases both with the height and depth from the surface of the Earth.	2. The value of $G$ is a universal constant. It remains same everywhere.
3 The value of $g$ is $9.8\frac{m}{s^2}$ near the surface of the earth.	3.The value of $G=6.67\times {10}^{-11}\frac{N{m}^2}{k{g}^2}$everywhere in the universe.
4. At the center of the earth, $g=0$	4. At every point on the earth, it's value remains constant.
