The gravitational acceleration on the moon is about one sixth the size of the gravitational on earth. according to newton's second law of motion, what happends to an astronaut who goes to the moon

Weight of a person on the earth is given by,

W= mg,

Where, g is the gravitational acceleration of the earth and m is the mass of the person.

Gravitational acceleration of the moon is one-sixth of the earth.

Therefore, the weight of a astronaut who goes to the moon will be one sixth of that on earth. Hence, the astronaut will weight less.
