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

First Blank: 40 kg, the mass of an object does not change. Mass is how much space an object takes up, therefore it does not change due to gravity.

Second Blank: 6.66 N. the gravity on the moon is nearly approximately 1/6 as Earth, so you just divide its normal weight on Earth, which is 40 kg, by 6 and fill it in.

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.
