On the Moon (where gravity is weaker than on Earth), an astronaut's MASS:
AIncreases
BDecreases
CBecomes zero
DStays the same
Answer & Solution
Correct answer: D. Stays the same
Mass is intrinsic to a body — it doesn't change with location. The astronaut's mass on Moon is the same as on Earth. Only WEIGHT changes — on the Moon, weight is ~1/6 of Earth's because gravity is weaker.
