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.

What is free fall?

Freefall is defined as a situation when a body is moving only under the influence of the earth’s gravity. Since external force is acting on the ball, the motion will be accelerated.

What is the value of g on the moon?

The value of acceleration due to gravity on the moon is one-sixth of its value on the earth. It is equal to 1.625 m/s2.
