Question

What is free fall. Using expression g=GM/R2 and knowing G, Calculate value of acceleration due

to gravity. Mass of earth=6x1024Kg Radius of earth=6.4x106m, G=6.67x10-11Nm2Kg-2

​

Answer 1

Free Fall is the downward motion under the influence of gravity.

$m = 6 \times {10}^{6} kg \\ r = 6.4 \times {10}^{6} m \\ g = 6.67 \times {10}^{ - 11} {kg}^{ - 2} \\ \\ g = \frac{6.67 \times {10}^{ - 11 \: } \times 6 \times {10}^{24}m\ {s}^{2} }{6.4 \times {10}^{6} \times 6.4 \times {10}^{6} } \\ g = 9.8m {s}^{2} ...your \: answer$
