If your weight is 120 pounds and your mass is 54 kilograms, how would those
values change if you were on the moon? The grav-
itational force on the moon is 1/6 the gravitational
force on Earth.

Explanation:

Weight is 120 pounds and mass is 54 kg

The mass of an object is same everywhere. If we were on the moon, its mass will remain to be 54 kg.

Weight of an object is given by :

g is acceleration due to gravity on that surface

For moon, it is 1/6 the gravitational  force on Earth, g = 1.63 m/s²

1 pound = 4.45 N

It means my weight is 533.78 N

On the surface of Moon is will be :
