[QUOTE="WildRose, post: 524207, member: 30902"] You feel the ball hit at the end because it came to a stop. When it did it's momentum drove the piple a little furter in the same direction. The energy of that ball has to go somewhere. A rifle with a plugged barrel acts in similar fasion with a much more dramatic effect because the pressure cannot be released otherwise. Conversely if that pipe wasn't capped and the ball continued to exit, no such effect would be possible. The energy of the ball goes with it. If you want to study inertia get on an old pinball machine. Launch a ball and see how far it goes vs how far the launch pin bounces back after impact. For something similar to how things react inside your barral buy a large 50 cc syringe. Draw 50cc's of air, then plug the end with caulk and let it set overnight. Now place the thumb end of the plunger on the table and depress the syringe downward. WHen you reach the point you can no longer compress the air release it. Of course there is no combustion going on with in the pressure vessel but it will expand quite rapidly until the trapped gasses cease expanding. This will also give you a good idea as to why we use powders that continue burning and generating pressure to at least the end of the barrel. [/QUOTE]
