No, not quite right, at least in conventional physics. Newton's Force law is F = m * A. A is acceleration or change in velocity divided by change
A g refers to the force exerted by earth's gravitational field at it's surface. Notice that if the velocity is constant, A = 0, since A = delta
velocity/ delta time. No change in velocity means no change in acceleration, means no force at all.
Thus you could be traveling at 99% of the speed of light and not experience any "g's". Of course you would be destroyed by space dust.
If on the other hand you had an antigravity device, then particles around you as well as your own body would experience forces proportional to their
masses and hence you would not experience any 'g's' for the same reason you don't feel any g's whilst free falling. Every atom in your body
experiences the same acceleration and thus there is no relative stress on your body.
Now in some alternative theories there is a 'friction' component to the force laws that depend on velocity. Weber's formulation of electromagnetic
theory has such a term, and it is provably a more accurate force law for electromagnetics.
