Question

Differentiate gravitational constant $G$ and acceleration gravity ${}^{\prime }{g}^{\prime }$.

Answer 1

The differences between G and g I as follows

(1) G is called as universal gravitational constant and g is acceleration due to gravity.

(2) The value of $G=6.67408\times {10}^{-11}{m}^{3}k{g}^{-1}{s}^{-2}$ while the value of $g=9.8m{s}^{-2}or10m{s}^{-2}$

(3) The value of G remains constant everywhere while that of g varies.

(4) G is a constant while g is the acceleration produced on a freely falling body.
