I read that if you are in a spaceship orbiting earth in a circular motion, the astronout feels weightless (meaning the normal force to the astronout is equal to zero). But according to newton laws equations you get:(adsbygoogle = window.adsbygoogle || []).push({});

and then if we assume N=0 (which is really what's happening according to my understanding), we get:

And I don't understand why is that true, if you can explain, or if there is any mistake in what i've said above,

Thanks
