In the consideration of rocket motion we always use the principle of the Conservation of Linear Momentum.This principle holds true only for isolated systems.But the initial stage of rocket motion is strongly affected by gravity-----which is definitely an external force [if we consider the rocket and the ejected fuel as the "system",as it is normally done in most typical calculations].
Do we expect to get accurate results after all this?
