The gas pressure in the barrel pushes both ways; against the gun and against the bullet. However, the bullet is not important for the rocket effect. The gas itself is accelerated, instead. Hans |

Proven right here that there is no equal and opposite force from gas movement due to pressure gradient force |

Try counting them again. |

Are you claiming that gas has no mass? |

By the way, several of the members posting in this thread already have considerable experience with posters who lapse into fractured English when they see their argument destroyed. It won’t work. |

Gingervytes, when you can take a break from pretending that Newton’s Third Law only applies when you find it convenient, would you be so kind as to answer the questions and refutations I’ve already put to you, but you have ignored so far? Here, I’ll repeat them for you:

Does the exhaust from a rocket expand equally in all directions? |

You were shown how the video conflates other physical effects such as gravity and buoyancy. You have not rehabilitated your argument in the face of that demonstration. Simply repeating a debunked claim does not overcome its refutation. |

Remember when self-styled super-engineer Anders was over on apollohoax, blithely not understanding conservation of energy? This reminds me of that, in particular the counterexample I gave him of a non-propulsive mass jettison. Dunning-Krueger in action.

Post 217, Gingervytes. Why won’t you answer the questions and refutations already provided you?

Nope. But answer the question: does the exhaust from a rocket expand equally in all directions? |

Quote:
After all, rockets have been successfully operating in the vacuum of space for well over 60 years now. In fact, if rockets could not operate in the vacuum of space, then it would not have been possible for the Apollo astronauts to go to the Moon and back in 1969 (plus a few more times after that). |

It’s not exactly rocket science. Quote:
Oh yeah, that’s right. |

There's a two-player Cheese Shop game in The Brand New Monty Python Bok, in which one player - the customer - asks for various different types of cheese, and the other - the shopkeeper - has to think up a new excuse as to why he hasn't got it. I think it's important, for those who are trying to persuade Gingervytes of his/her error, to realise that he/she is not seeking information or correction here, but playing a variant of the Cheese Shop game, in the role of shopkeeper.
