How Does Mass Affect Weight? | Gravity Science Lesson

For example, a rock that weighs one pound while on Earth will weigh less than that if it is taken to the moon. But does its mass change just because it is on the moon? No, it is still the same size and looks the same, it just has less gravity pulling on it, so it weighs less.
