I unit = ms-2 • g does not depends on the mass of the falling object or smaller masses. • Force exerted by the earth on the body. • F = GMm/R2 • This force by earth produces acceleration in the stone due to which stone moves downwards. • Force = mass x acceleration • F = m x a • GMm/R2 = m x a • a = GM/R2 • Here, a = g • g = GM/R2 • g = (6.67 x 10-11 Nm2/kg2 x 6 x 1024 kg)/6.4 x 106 m • g = 9.8 ms-2 . • Disclaimer: This video is for educational and informational purposes only and is not intended to infringe on any copyrights.
