Physics question

If gravity, friction etc not affecting either ball there is nothing to stop either one. They both continue to travel until something stops their momentum.

Is that correct MrPrena?

Only thing it eventually stopping those 2 masses are gravity (g=9.8m/s^2) when it hit the ground some day.

Now, if those 2 items were thrown in the space without any gravity affecting it, it need reaction of same force to stop them.

Yes, but if they were thrown in space around earth they would need a lot more velocity thsn 40mph to not fall back down.

Without gravity.
However you are absolutely right. I would not know any empty space which has pure zero gravity within x parsec.

Spacestation has about 94-95% earth'a gravity by doing univ gravity equn.
Even Neptune is effected by suns gravity.
Heck. Even the galaxy is spinning around the center.
