## Main Question or Discussion Point

so a pilot is spining in a circle at a constant speed, the g forces he will feel will be the same than normal acceleration dependant on wr

but now you put him inside a tube where he can move along varying the radius of the circle

now the normal acceleration will be zero because he is in the equivalent of centrifugal gravity free fall

but he will feel as g forces the tangential acceleration as tangential velocity is function of wr and r is increasing as the pilot moves along the tube

but now you propel the spining tube in such a way than as the pilot doubles radius the w velocity of the tube halves, on this way the tangential velocity is constant and hence tangential acceleration is zero

but how can the pilot be in this last case in zero tangential acceleration and zero normal acceleration which implies he endures zero g forces if he is making a spiral trajectory?
