Why does your mass stay the same if you go to the moon?

Answer 1

Oh, dude, your mass stays the same on the moon because mass is a measure of the amount of matter in your body, and that doesn't change just because you're chilling on a different celestial body. Your weight, on the other hand, would be less on the moon because gravity there is weaker. So, like, you might feel lighter and more floaty, but your mass is still the same old you.

Answer 2

Mass is not the same as weight. Your weight will be less on the Moon; your mass can informally be considered as the "amount of substance" you have. Since you won't lose or gain a significant amount of atoms when you go to the Moon, your mass will stay the same - except for any insignificant change if you eat or breathe on your trip to the Moon, or an even more insignificant effect due to the General Theory of Relativity.

Answer 3

Because nothing about ME changes by going to the moon. Mass is a fundamental property of matter, which does not change just because I go somewhere else.

It is very easy to be confused by the fact that mass and weight have the same units. There is no theoretical reason why this should be. There is a good practical reason, which is that it is much easier to measure weight than mass, and the two are equivalent as long as we stay on the surface of our very own planet.

Consider an astronaut. While on the space station she has no weight; she can float in mid air. Suppose she starts from one end of the station's long axis, and uses her legs to push off as hard as she can towards the far end. She is now in big trouble.

She needs to turn in mid flight so that her feet hit the far wall first, then cushion an impact that will be at least as bad as stepping off the top of a six foot wall while on earth. Unless she is a practised gymnast she will at least risk sprains and very possibly fractures to her feet, ankles and legs. If she didn't make the turn to land feet-first she risks a broken neck. All this because she still has her normal mass, and normal kinetic energy.

Come to the moon with me ! You will be able to lift me over your head because I weigh 30 pounds. Put me back on my feet and punch me in the chest, hard. Should be easy to knock me flat, me being a 30 lb weakling. Nice try, but my mass is still 200 lbs. I'm still standing, and still smiling, knowingly.

Answer 4

Mass is the amount of particles that you have, i.e. how big you are.

being on the moon doesn't make you thinner or fatter, so you mass stays the same

Weight on the other hand will change on the moon. weight is a force you fell, which pulls you down to the ground. The moon is smaller than earth so the pulling force is smaller, therefore your weight changes and you feel lighter. but you will still be fat.(i.e the same size)

Answer 6

Your mass remains the same because it is determined by the amount of matter in your body, which doesn't change when you travel to the moon. However, your weight would be different on the moon due to the moon's lower gravitational pull compared to Earth.

Answer 7

Why should it? Mass is (informally) the "amount of substance", and there is no reason why you should lose or gain substance (e.g., atoms) when moving to the moon.
