what makes planes fly? | plane uses Bernoulli's principle that the thrust increases where pressure are unbalanced and they will gain lift and that is how a plane fly! |
What are the proper3 principles of air | air has space air has mass and air has pressure |
how do the airfoil work? | airfoil works like this: the air on top of the wing moves faster and the bottom goes slower, so that kinda creates less drag, and the atoms on the bottom of the wing create lift and the atoms push the plane up. |
how do birds fly? | Birds first jump and that creates some thrust up and then they will flap their wings and that creates thrust and lift, so they jump for a head start. |
why do some planes need bigger wings? | because some planes are very heavy so the bigger the wings the more atoms will push the plane up. |
