Why do planes stay in the air instead of falling?

Planes stay in the air because their wings push the air down, and the air pushes them up, like when you jump on a trampoline and it sends you flying.

Imagine your wings are like giant fans. When a plane moves forward, its wings push air downward. Because of this, the air pushes back up, helping the plane stay in the sky. This is called lift, the force that makes planes rise and fly.

Think about when you blow on a piece of paper. It flaps up because the air you're pushing down creates an upward push. Planes work the same way, but much bigger! Their wings are shaped in a special way so they can push more air down as they move forward.

When the lift is strong enough to match the weight of the plane, it floats like a balloon, no need to fall!
