Comment on When you inhale helium from a balloon, do you weigh less?
pixeltree@lemmy.blahaj.zone 2 months agoLess the difference between weight and mass and more the affect of buoyancy on your method of measurement. If you float in water, it doesn’t mean you’re weightless in water. It just means the buoyant force of the water overpowers gravity.

That is exactly the difference between weight and mass. And yes, that would be weightless and objects like balloons have negative weight until they reach an altitude where they’re neutrally bouyant and then are weightless.
en.m.wikipedia.org/wiki/Weight
Weight is defined as a force and has a direction. That’s what causes the movement. If the weight didn’t change there would be no movement.
