RE: Do rockets work in Space?

in #science8 years ago

When the gas comes out the tail if the rocket it does not need to push against anything. It's not like a bird or jet that is moving air to push itself forward. A rocket is a chemical reaction that creates it's own gas. The gas moving in one direction pushes the rocket in the other. Equal and opposite.

Sort:  

gas coming out the tail of a rocket is the same effect as a bullet coming out the barrel of a gun.

recoil.

  • a rocket doesn't move by shooting bullets; if that were the case I would have long agreed to the validity of the propulsion;
  • it moves by pushing it's own fluid out and away from itself, but into what? what is the resistance of it's surroundings? on what it pushes? does it's exhaust change the Void into non-Void?
  • here's 3 clips if anyone is interested about propulsion in Void(Vacuum effect on higher pressure systems) and also bullets...


A rocket would work if it fired bullets and yes guns do work in space even. The gas escaping pushes against the rocket. Gas goes in direction A Rocket goes in opposite direction B. Equal and opposite reaction. The mass of the rocket (and remaining fuel) is what the gas produced by the fuel pushes against not the vacuum of space. You have to think of every part of the rocket as separate not one object pushing against space.
