1) An object will maintain its momentum forever unless some force acts upon it.

2) In the case of the rocket, it accelerates eastward. Even if parts fall off, and they slow down because of the drag of the atmosphere, and they slow down all the way to the speed of the atmosphere, the atmosphere is more or less moving eastward at the same speed as the earth's rotation, so any part would be unlikely to land any further west than where it detached from the rocket. And if there was no atmosphere on earth any part that fell off a rocket during its ascent to orbit would fall according to a ballistic trajectory and would most certainly land farther east than where it fell.

So there's no friction from the atmosphere?
"friction from the atmosphere" = drag. The previous commenter explains the effect friction has.
