Well...all of this has been about you attacking me for correcting the guy on his physics understanding, so I am assuming you must have a position on it. Do YOU think that the whole ISS/space shuttle thing is a hoax?
Right, you just said that I was unqualified to post any info on how rocketry works because I am not a "Rocket Scientist". Funny. Do you ever contribute any substantive rebuttals in any of your postings?
Kind of pointless seeing as you cant see "any benefits from the space station". Such short-sightedness is alarming. Perhaps you should google their press kit sometime. Well, goodnight, I am off to do some thing more productive....like my girlfriend.
Newton's Third Law of Motion states that every action has an equal and opposite reaction.
Contained within the Third Law is also the law of the conservation of momentum.
As exhaust is thrust out of the back of the rocket this exhaust has a momentum which is equal to its mass multiplied by the exhaust velocity. It follows from this that the higher the exhaust velocity the greater the momentum of the rocket exhaust and hence the greater the thrust.
Because of Newton's Third Law half of the momentum of this rocket exhaust will be used to push the rocket in the opposite direction.
If you know the rocket's mass, the amount of fuel burnt per second and the exhaust velocity then you can calculate the rocket's gain in velocity per second interval which is also therefore equal to its acceleration.
