If your weight is 48 kg on earth what will. The weight on moon.

$\huge \star \: { \boxed{ \underline{ \tt{ \pink{Answer}}}}}$

Confusion in terminology:

• If you are a 48 kg person on earth , you will be a 48kg person on the moon . Mass is constant and does not change.

But on earth where acceleration due to gravity is 9.81m/s² ( an accepted value for working) then your weight on earth will be

$\sf \: Weight = mass \times acceleration \: due \: to \: gravity$

$\sf \: weight = 48kg \times 9.81 m/s² = 471N$

And on the moon where acceleration due to gravity = 1.625 m/s²

$\sf \: Weight \: on \: moon = 48kg \times 1.625m/s² = 78N$

What is the weight of gravity on the moon?

• The moon's mass—the amount of material that makes up the moon—is about one-eightieth of the Earth's mass. Because the force of gravity at the surface of an object is the result of the object's mass and size, the surface gravity of the moon is only one-sixth that of the Earth.

Weight of an object on the Moon:-

• Just as the weight of an object on the earth is the force with which the earth attracts the object, in the same way , the weight of an object on the moon is the force with which the moon attracts that object.
• The gravitational force of the moon is about one-sixth hat of earth.
• Therefore, the weight of an object on the moon will be about one-sixth of what it is on earth.
