Question

gravity on earth is 9.8 m/s², and gravity on the moon is 1.6 m/s². so, if the mass of an object on earth is 40 kilograms, its mass on the moon is \boxed{} kilograms and its weight on the moon is \boxed{} newtons.

Explanation:

Answer:

40
64

(Note: Mass is invariant, so the mass on the Moon is the same as on Earth, 40 kg. Weight is calculated as mass × gravity, so \( 40 \, \text{kg} \times 1.6 \, \text{m/s}^2 = 64 \, \text{N} \).)
