STFU.Back to real science:A rocket in space very much resembles a pressurised vessel separated from a vacuum by a valve.Which is remarkably similar to the conditions of the Joule free expansion experiment.Once the valve of the Joule expansion experiment was opened, the pressurised gas released into the vacuum was found to do no work.http://pubs.acs.org/doi/pdf/10.1021/j150043a002http://web.mit.edu/16.unified/www/FALL/thermodynamics/notes/node33.htmlhttp://www.etomica.org/app/modules/sites/JouleThomson/Background2.htmlThis proves a gas-powered rocket would also do no work in a vacuum.PROVES, markjo.Here is the definition of 'work':http://hyperphysics.phy-astr.gsu.edu/hbase/work.htmlNo work=no force=no movement.Game fucking over shills.
STFU.

^Time wasting but un-bannable shill.
Joule free experiment - closedRocket - open

Conservation of momentum dictates that if material is ejected backward, the forward momentum of the remaining rocket must increase since an isolated system cannot change its net momentum. http://hyperphysics.phy-astr.gsu.edu/hbase/rocket.html#c3LOL!!!You hopeless freaks simply cannot get your bullshit straight can you?

Quote from: Mainframes on July 13, 2016, 02:54:35 PMIsolated system =/= closed systemThat is all.No, an isolated system is a closed one, it's just there are two different ways to define the system, 1. All the mass that was originally inside the rocket stays a part of the system. This is a closed system. 2. Once the mass has left the rocket, it leaves the system. This is an open system.
Isolated system =/= closed systemThat is all.
I ask again, why is momentum not conserved?
Quote from: Definitely Not Official on July 16, 2016, 09:06:03 AMI ask again, why is momentum not conserved?Because there's no such thing as an environment (known to us) that can give rise to conservation of momentum. There will ALWAYS be a resistance to any action/motion.

No work=no force=no movement.
Besides, perhaps FET is a conspiracy too.
It is just the way it is, you understanding it doesn't concern me.
Papa legba don't you understand that science is built-in machine,one way ticket to meaningless All what you can do with science is one big delusion, people are slaves of the delusion,the scientists are slaves of the delusion,the entities of this delusion feed us with nothing.
What will I find if I dare open this post? Re: Newtons third law « Reply #1558 on: Today at 12:04:50 PM »You are ignoring this user.Probably just more "Regurgitated Copy Pasta"!So it's not much point!
STFU it is bullshit proven shill-forum Fuck off; this is all you'll get from now on:Game fucking over shills.
So far, Papa definitely doesn't understand Newton's third law. And I am not sure if it will be possible to teach him. Maybe if we do it in small steps...Papa Legba, if you were to fire a gun in space, would it recoil?

Do you mean that water talks to dead spirits?
