Question

The value of g on the surface of moon is_________

Answer 1

Acceleration due to gravity

1. ‘g’ is used to denote acceleration due to gravity.
2. It is the acceleration of a free-falling object.
3. The value of g on earth is $9.81m{s}^{-2}$.

Explanation

1. The gravity of the moon is $16.6\%$ of Earth's gravity.
2. Acceleration due to gravity on the moon will be $16.6\%$ of g on earth.

$$\begin{gathered} g_{moon}=16.6\%\times g_{Earth} \\ {g}_{moon}=\frac{16.6}{100}\times 9.81 \\ {g}_{moon}=0.166\times 9.81 \\ {g}_{moon}=1.625m{s}^{-2}approx \end{gathered}$$

The value of g on the surface of the moon is 1.625 m/s².
