Quizplus · Accepted Answer

Mass is a measure of the amount of matter in an object and does not change with location. Weight is the force exerted by gravity on an object and varies with the strength of the gravitational field. Since the Moon's gravitational pull is weaker than Earth's, an astronaut's weight is less on the Moon, but their mass remains unchanged.
