The acceleration due to gravity is equal to second squared. (round to 2 significant digits)

Answer: g = 9,81 m/s^2 (average value for g in the Earth)

Explanation: The value of g depend on the localization on the Earth for example at the poles g is equal to: 9.83 m/s^2

On the other hand, at the aquator g=9.78 m/s^2
