A person of mass 60 kg weighs 588 N on the Earth. On the Moon, where g = 1.625 m s⁻², the same person will have
AA smaller mass and a smaller weight
BA larger mass and the same weight
CThe same mass and the same weight
DThe same mass but a smaller weight
Answer & Solution
Correct answer: D. The same mass but a smaller weight
1. Mass measures the matter in a body and does not change with location, so it stays 60 kg.
2. Weight W = mg depends on g, which is much smaller on the Moon.
3. So weight falls to 60 x 1.625 = 97.5 N while mass remains 60 kg.
4. Rule out option A: only weight decreases; mass is unchanged on the Moon.
