Where will an astronaut weigh most? (Moon or Earth) Why?
How much difference is there between the astronauts's masson Earth and on the moon?

this is simple...
weigh = mass x force of gravity
since Moon has smaller force of gravity, weight will be smaller on the Moon
mass is always the same, so, there is no difference between Earth and Moon

An astronaut will weight the most on the Earth, as Earth is larger and has a stronger gravitational pull. When the astronaut is on the moon, he/she will weigh approximately 1/6 his weight on Earth, because the moon has 1/6 of Earth's gravitational pull.
However, the mass of the astronaut on the Earth and the moon will be the same. Why? Mass measures how much matter the astronaut has. The astronaut will have the same amount of matter on the moon and the Earth. Weight measures gravitational pull, although on Earth, both mass and weight are calculated using the same mechanism.

Because the moon has less mass than the Earth, it has a smaller gravitational effect. On the surface of the moon, the level of gravity is only about one-sixth of that on Earth. A person who weighs 100 pounds on Earth would weigh only 17 pounds if they stood on a scale on the moon.

will weigh more on moon, weight is a measure of the force gravity has on a mass, gxm=w,gravity as force is lower on the moon, the mass is the same assuming the astroguy did not get fat or starve on the trip,so he is just as big, he is just as hard to stop if he runs into a wall etc. but he is easier to lift and carry, not because he is changed but because the moons gravity doesn't pull him down to the moon as hard as earths gravity would, gravity is related to the size of the things that are reacting to it, the smaller earth shows less force of gravity than the larger sun, the smaller moon has less force of gravity than the larger earth
mass change of astroboy is considered to be nothing

weigh more on earth--stronger gravitational pull. mass is the same on both the earth and the moon.

Earth, because of gravitation.
