What would be the mass of a 70 kg man on the moon as well as on the earth? Take g = 9.8m/s2 for earth, and g = 1.63 m/s2 for the moon.
A
:
105.0 kg on Moon and 70 kg on Earth
B
:
140.0 kg on Moon and 70 kg on Earth
C
:
70.0 kg on both Moon and Earth
D
:
35.0 kg on Moon and 70 kg on Earth

Gravity
Answer
Option 3 : 70.0 kg on both Moon and Earth
Explanation
- Mass of a body is constant everywhere in the universe, so the mass of this 70 kg man would be the same on the earth as well as on the moon.
Additional Information
- Weight is a measure of how much gravity pulls on a mass or object.
- On the moon, there is less gravity pulling on objects, so they weigh less.
- Mass remains the same on moon and earth while weight change with gravity.
