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 ????? kilograms and its weight on the Moon is ???? newtons.

Answer 1

the weight of the object on the moon is 64 N and the mass on the moon is 40 kg

i got it right

Answer 2

The mass of an object on Earth is the same as its mass on the Moon. The weight is different.
Weight = m * g
Weight ( Moon ) = 40 kg * 1.6 m/s² = 64 N
If the mass of an object on Earth is 40 kg, its mass on the Moon is 40 kg and its weight on the Moon is 64 N.
