You would be assuming a quantum leap type theory, that the object has no
Vo->V1, it just adjusts to the constant immediately, instead of what I
would call the quantum leap,without other 'theories' involved, that it has
a classical physics type movement in which it can accelerate from a resting
position, to a velocity, and then regain orbit:
