On the Moon, g = 1.6 N/kg. In other words, a 1 kg mass has a weight on the Moon of 1.6 N. The weight of the girl on the Moon is 72 N. The mass of the girl is the same on the Earth and the Moon ...

This means that for each kg of mass, an object will experience 9.8 N of force. Where there is a weaker gravitational field, the weight of an object is smaller. For example, the gravitational field ...
