Question #1152
The Earth has a mass of 5.98 x 10^24 kg and its mean radius is 6.37 x 10^6 m. Using these values, calculate the acceleration due to gravity at the surface of the Earth.
Expert's answer
We can calculate the gravity acceleration as
a = GM/R2 = 6.67x10-11 * 5.98x1024 /( 6.37x 106 )2 = 9.82 m/s2.
