Airplanes exploit a loophole in the physics of air pressure. It's a mundane sort of thing, compared to being IN a plane, but essentially, air gets bottlenecked trying to go around an airfoil (such as the wing of a plane) and more ends up being pushed up, into the wing from below, rather than flowing over it smoothly. Helicopters use their rotors to pull air down in a column, like a ceiling fan. They almost ride the column of air like a man climbing a rope. Hot-air-balloons heat air in a sealed environment and rise because hot air is less dense than cold air.
It makes it fly
no it weighs things down . Hot air tends to lift things, as in a hot air balloon.
Convex lens makes things look bigger and concave lens makes things look smaller!
Pressure builds up, and when it is released it forces the rocket up.
The force that makes things pull downwards is called "gravity". That's why we don't float when we jump.
Lift and speed are the two major things that makes an airplane fly. When enough speed is created to push enough air under the wings, the craft will lift off the ground.
Lift makes paper airplanes fly, just as it does real planes.magic
A fly-swatter works for me
maple seeds work by air presure. Air pressure makes things fly such as maple seeds.
Most things with wings can fly.
A fly is considered an invertebrate because it does not have a backbone.
clouds
its engines
they can not fly
there wings
The thing that makes you leg fly is Joseph William Jeremier Cuthbert Humping it Hope That Helps :)
The same thing that makes a monoplane fly (i.e. lift), except a biplane has twice as many wings to do it with.
