NASA Thrust Equation gets destroyed. | |
Dr. Deplorable Astromut Senior Forum Moderator 03/07/2019 08:54 AM Report Abusive Post Report Copyright Violation | Even this source says that it pushes off the atmosphere. Does physics teach fluid dynamics? Why is it all the chemists that realize rockets don’t work in space? Quoting: Anonymous Coward 77120569 [link to www.chemed.org (secure)] “According to Newton's Third Law of Motion, every action has an equal and opposite reaction. Therefore, as the gas is released from the balloon, it pushes against the outside air, and the outside air pushes back. As a result, the rocket is propelled forward by the opposing force.” That explanation is not correct for balloons. Balloons are not rockets. The body of the balloon changes shape; it becomes smaller as the gas escapes. The outside air pushes around the body of the balloon and makes it move forward, like squeezing a wet bar of soap in your hand propels the soap. The body of a rocket does not behave like a balloon. That’s not what nasa and mainstream science says [link to www.homesciencetools.com (secure)] See where this is going? You people have contradicted yourselves while going nuts tying to prove that rockets work in space. You just can’t do it because it’s a lie The action of the exhaust leaving the rocket nozzle produces an opposite reaction of the rocket traveling in the opposite direction. I'm sorry you're too stupid to understand basic physics but Rockets do work in space and they have been filmed working in Space by amateurs including myself. |

Quoting: The Rickest Rick Sanchez I don't want to spend the effort to disprove a failed disproving. The burden is yours and it was not achieved. You basically gave up after flipping equations and describing a vague unrelated experiment. So your too lazy to disprove the evidence provided so we should just take your word for it? Right You've already demonstrated that there is *no proof* you will accept. So, what's the point? You handwave away every evidence. If I am incorrect, please spell out *completely* what specific evidence would prove *to you* that rockets work in space. If there is none, it is pointless to engage. But what proof have you provided? Fake edited and cut videos. So far you have neither Been able to debunk the video nor provide actual evidence of rockets in space. See? You avoid my challenge altogether. When Astro provided motion captures of a satellite firing a thruster in space taken by a telescope, you call it fake (with no evidence to, of course, back that up). When you can see the ISS in orbit with your naked eye, and Space X docking with it, you yell fake again. You won't even go to sites identifying satellites you can see from your very spot on Earth and *look up.* There is *no evidence* you'll accept. None. If you want to prove me wrong, spell out exactly what evidence you WOULD accept. And imagine my shock when you don't. |

The exit velocity came from a relative velocity of zero to exit velocity. That is acceleration, not constant velocity. The acceleration of the fuel is the force. Doesnt matter if its in water, air, or nothing. The op is not keeping track of time units in his assumptions. |

Already, the bar has been set quite high that it would have to be the largest vacuum chamber in the world, because all other vacuums are, apparently, too small. That's a tall order. |

Newton: For every action there is an equal but opposite reaction. ......... OP let me guess. Your level of education is non existent, right? Fucking idiot. Let me really bake that little noodle that passes as a brain. Do you even know that the density of the gas that a rocket produces is even lower than the air around it?.... LOL, I guess your mind fucked now in a low IQ mire. It is all about velocity and mass. ......... Mass being ejected out the back of the rocket at a massive velocity that overcomes the mass of the rocket itself. Like the recoil of a gun, only with rockets the recoil is sustained. |
