 # Value Of g On Moon

The acceleration experienced by a freely falling object due to the gravitational force of the massive body is called acceleration due to gravity and is represented by g measured using SI unit m/s2. The value of g depends on the mass of the massive body and its radius and its value varies from one body to another. The value of g on the moon is constant.

## Acceleration due to gravity on moon

The acceleration due to gravity on moon or the value of g on moon is 1.625 m/s2.

### Calculate acceleration due to gravity on moon

The acceleration due to gravity formula is given by

$$\begin{array}{l}g=\frac{GM}{R^{2}}\end{array}$$

Where,

• G is the universal gravitational constant, G = 6.674×10-11m3kg-1s-2.
• M is the mass of the massive body measured using kg.
• R is the radius of the massive body measured using m.
• g is the acceleration due to gravity measured using m/s2.

The mass of the moon is 7.35×1022kg.

The radius of the moon is 1.74×10m

Substituting the values in the formula we get-

$$\begin{array}{l}g=\frac{6.67\times 10^{-11}\times 7.35\times 10^{22}}{\left ( 1.74\times 10^{6} \right )^{2}}\end{array}$$

Thus, the value of g on moon is g=1.625 m/s2.

The acceleration due to gravity also follows the unit of acceleration

Hope you got to know the value of g on the moon along with acceleration due to the gravity formula, definition, calculation, and SI units.
