Airplanes fly because they push air down, and that pushes them up, just like when you jump on a trampoline!
Airplanes have wings, which are like the big flat parts on top of them. These wings work kind of like a big fan. When the airplane moves forward, air flows over the top and bottom of the wing.
The shape of the wing makes the air move faster on top than underneath. Faster-moving air means less pressure, so there’s more push from below than above. This difference in pressure is what makes the airplane lift into the sky!
How wings work
Imagine you're blowing on a paper strip. If you blow hard over the top of it, it lifts up, that's how air pressure works! The same thing happens with airplane wings: more push from below means lift, and that’s what helps the plane go up.
Airplanes also have engines that make them move forward. When they’re moving fast enough, the air gets pushed down by the wings, and the airplane goes up like a superhero on a flying carpet! Airplanes fly because they push air down, and that pushes them up, just like when you jump on a trampoline!
