sure but not for any of the potsmoke reasons you listed

intertia is the byproduct of us being in a translational universe. inertia and momentum can be thought of as the movement force. A heavy object resists having its position changed, but still accepts positional energy or movement force when you push on it. Think of a boulder, one that you can barely lean but definitely not pick up or push over. When you put energy into that boulder it moves but doesn't keep moving, it only moves as much as the energy you put in allows vs. its self momentum under its own weight.

So when you throw an apple what you've really done is put more movement energy into the apple than is necessary for it to only move slightly and then stop.

in space without friction from gravity, air, or anything else, momentum is carried further. maybe what confuses you isn't inertia but the fact that some systems have a lower state of entropy than what is otherwise conventional. Yes our universe conserves vectors of motion if there isn't an adequate resistance in the way, but all atoms have a half life and as such eventually self resistance will become a thing for an object moving through empty space forever
