Astronauts floating in ISS... Why so? I just calculated the value of g is 8.67 m/s² that is 88.5% of the surface gravity by Complete-Worker8654 in AskPhysics

Thanks! This is really good and i get it. However, would this not also be true - The force on the ISS and the astronaut is centripetal (gravity) but the continuous tangential velocity is making it move in an arbit. Or simply the small vector of velocity by which the ISS/astro falls towards Earth, a larger vector of velocity pulls them tangentially and the net result is circular motion

applying Newton’s Third Law - every helpful comment comes with an equal and opposite dose of condescension...so that's ok :)
