I read over the mass, yes, it would be 81kg. Mass does not change.
- 1 decade ago
Explanation: This question asks about mass, according to the conversation of mass law, mass will never change (unless converted to energy) so 81 kg on earth = 81 kg on the moon, weight (and force) however is different because of the differing forces of gravity on/ of bodies of matter.
Answer: 81 kg
Many people will assume that weight and mass are the same thing... its not
Source(s): To understand the differences we need to compare a few points: 1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object. 2) Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale. 3) The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location. from: http://www.nyu.edu/pages/mathmol/textbook/weightvm... - FiremanLv 71 decade ago
On moon g' = g/6
=>The weight of woman on moon (W') = m x g' = 81 x 9.8/6 = 132.3 N
