Is there a relationship between an objects mass and its weight?

Answer 1

Yes, of course. Mass is an intrinsic property of matter. Weight is something we usually measure with a scale, and it depends on gravity. For example, if I weighed you here, on Earth, you'd weigh what your scale says you weigh (assuming that it's accurate). But if we were to take the whole show to the moon, you'd weigh about one sixth of that, even though you have exactly the same mass. The difference is that the gravity on the moon is much less than that on earth ( about 1/6 th).
