NASA Thrust Equation gets destroyed. | |

Quoting: Anonymous Coward 77446242 The vacuum cleaner simply creates low pressure, that is all. [link to www.quora.com (secure)] The equation stated that there is force due to mass flow rate exiting a pipe. There is flow rate exiting the pipe. Where is the force observed? Air is moving due to difference in pressure caused by the vacuum cleaner. We have mass and acceleration, force. The acceleration caused by pressure differential is pressure gradient force, not because the rocket pushes it out. Just like gravity, it doesn’t need to push off anything. [link to en.m.wikipedia.org (secure)] Pressure difference is how the rocket pushes it out, and how the vacuum cleaner lifts, and how wings and propellers lift. Newton's third law applies to all of them and to gravity. That’s like saying when you spill a cup of water by turning it upside down there is an opposite reaction on the cup |

Pilgrim001 User ID: 77021014 United States 03/11/2019 05:47 PM Report Abusive Post Report Copyright Violation | Chemical rocket thrust does not work in the vacuum of space. Quoting: Idaho Bullwinkle Near the Earth, rocket thrust pushes against the atmosphere around the rocket. In space, rocket thrust pushes against NOTHING. If Chemical rockets can push against nothing, you should be able to fly if you pull hard enough on your shoe laces. No computer or maybe ALL the computers in the world working together can not resolve a 3 body space problem. All bodies in the conventionally accepted space model are claimed to be moving through the universe between 800,000 mph to 2.2 million mph. No body knows the exact speeds so nobody can calculate the movement of a third body to go from on moving mass to another moving mass. I do not KNOW the nature of those lights in the sky. People through mass indoctrination ASSUME that the lights are satellites created and launched by man. Did you take physics in college? I'm thinking NO. I don't have the time or the crayons to explain this to you. Slake Blake |

Quoting: Anonymous Coward 77414673 Bad interpretations of facts, even using math, can be BS, though. It’s not bs. The fluid dynamics equation is used in Many industries. The velocity of gas in the nozzle pipe is equal to the exit velocity. ...and it is mass that's being accelerated out of the combustion chamber and out of the rocket engine nozzle. The fuel and oxidizer molecules don't just "go away" at ignition. In a vacuum I do not think that you can even have combustion. Above and below certain saturation levels combustion can not take place depending on the combustible. And, in a vacuum the molecules do just go away as the molecules of combustion have zero resistance. The molecules would be absorbed by a vacuum faster than they can be ejected from a rocket engine. You are all just making assumptions based on a belief without a verifiable demonstration Have you ever been shown a demonstration of escaping gas moving an object in a vacuum chamber? Also, mathematics can be used to prove a lie as well as the truth. The experiment claiming to have derived the gravitational constant has never been successfully duplicated to prove the number is correct. There has never been an attraction of two bodies in a vacuum observed. It is in the interests of the ruling class that the peasants do not learn how to think. That is enough from me trying to cast pearls before swine. "In a vacuum I do not think that you can even have combustion." Well, there it is. It's funny you should mention pearls before swine. I don't have the time or the crayons to explain this to you. Slake Blake |

With buoyancy, weight is transferred to the object floating up from the water it was displacing. It is correct no external change in weight should show on the scale. Pressure gradient force can cause movement of a fluid mass having momentum which is conserved meaning that momentum will be transferred to another mass in contact, like a rocket.
