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 !!!
In: Physics
Weight is to mass as interest is to money.
Imagine for a moment that for the past ten thousand years there was only one rate of interest- 10% a year. Sure you could imagine the rate would be different but come on, it never actually is. So when someone says interest is a hundred bucks a year you know the money is 1000. It’s just… Known…
Well that’s the weight thing. Weight is mass x acceleration and acceleration is always always always gravity. So you start to think of these things as the same thing. But they are not.
When acceleration increases by more than gravity weight goes up but mass stays the same.
