Question

differentiate between gravitational constant G and acceleration due to gravity g

Answer 1

gravitational constant(G)
                                       the value is constant at every place whreas acceleration due to gravity is changing when we move from equator to poles.
si unit ofG is kgm/s2 ,si unit of  g is m/s2

Answer 2

Gravitational Acceleration: g = (G × Mass)/(distance from the center)2. Comparing gravitational accelerations: acceleration at position A = acceleration at position B × (distance B/distance A)2.
