Question

What is the value of $\mathrm{g}$ on the surface of the moon?

Answer 1

1. When an object falls headlong into the surface of the Earth from a certain height, its speed changes.
2. This change in speed is due to the acceleration known as acceleration due to the force of gravity denoted by the letter $\mathrm{g}$.
3. The value of $\mathrm{g}$ on the surface of the moon is $g_{Moon}=\frac{1}{6}{g}_{Earth}$.
4. The acceleration due to gravity on the earth is $9.8m{s}^{-2}$.
5. Thus, the acceleration due to gravity on the moon is $g_{Moon}=\frac{9.8}{6}=1.63m{s}^{-2}$
6. Hence, the value of $\mathrm{g}$ on the surface of the moon is $1.63m{s}^{-2}$.
