Eli5: Weight vs mass in space

825 views

Explain like I’m 5. Ok I’m confused. If I “weigh” 100 lbs on earth it is due to the pull of the earths gravity on my body. But in space I’d be weightless. So how do you calculate mass of something in space ? All this thought because of the new toilet going up to the space station !!!

Weight I believe is directional. Gravity is pulling us down by an amount scaled by our mass. In space, you’re not pulled in any specific direction. A 500 lb object is weightless, but imagine trying to push it. It wouldn’t be easy.
