Simple proof, rockets don’t work in space vacuum: get a pipe with only one side open. Put closed face down on a scale. Remove the air from the pipe with vacuum. Where is the opposite force on the scale? I didn’t see it.
Now lets say you put an object, let say a few pennies that weight approx 3 grams each. Now the airflow is strong enough to lift those pennies against gravity. Shouldn’t I see a force greater than the normal force of the pennies?
Quoting: Balance242 Not sure if Trolling or Stupid, however I'll give you the benefit of the doubt. Your pipe analogy is stupid, The air would be removed and the weight of that air would be reflected in the scale weight, just because their is no air in the tube does not mean the penny is now massless, or can somehow overcome gravity. What airflow are you talking about? its either a vacuum chamber or a low pressure area, have you been taking meds and playing with vacuum cleaners??
