Question

If an object weighed 0.50 newtons on the moon what would its mass be on earth?

Answer 1

The acceleration of gravity on the Moon is
`g=1.62 m/s^2`. The weight W is related to the mass of the object m by the relationship

`W=mg`
If we rearrange it and we use
`W=0.50 N`, we find the mass of the object on the Moon:

`m= (W)/(g)= (0.5 N)/(1.62 m/s^2)=0.3 kg`

But the mass is an intrinsic property of an object, therefore it does not change if we are on the Moon or on Earth: therefore, 0.3 kg is also the mass of the object on Earth.
