Rocket Air
Why does a helicopter need to be in air to fly, but a rocket does not?
Why does a helicopter need to be in air to fly, but a rocket does not?
CHOOSE ALL THAT APPLY.
[ ] Helicopter flies by the propeller grabbing air above the propeller, and throwing the air down.
[ ] A rocket does need air to fly.
[ ] Helicopter needs something to throw down, but it doesn't carry its own stuff to throw.
[ ] The rocket uses N3 to fly, but the helicopter does not
[ ] The rocket carries its own stuff to throw down-the fuel inside the rocket.
[ ] A helicopter doesn't need air to fly, that's why helicopters can go above the atmosphere.
[ ] The rocket needs something below it, like a landing pad, or air below it to fly.
[ ] The helicopter needs something below it, like a landing pad, or air below it, to fly
Trues: 1, 3, 4, 5, 8
Falses: 2, 6, 7
Helicopters produce lift by compressing the air when it is pulled from above and pushed below.
Rockets produce thrust by combustion of materials that are released through nozzles (restricted channels).
To begin flight, they actually both have to have something below them, but only to build enough lift and thrust to overcome inertia. After that, only the helicopter has to maintain something below because without more air below, there would be no compression.
