What condtions u need for zero gravity state?

  1. Aug 28, 2011 #1
    i read that if u r in "spaceship" thats for example has circular orbit around earth - than u r in a zero gravity state.
    but from newton law u get this equations :
    mMG/R^2-N=mV^2/R

    so from this i get that N equal MG/R^2-V^2/R
    and why would MG/R^2-V^2/R be zero ? no metter what?

    I'm sorry, what you wrote is incomprehensible. Please try again, without the text-speak and explaining what your terms mean.
