How Does The Four Forces of Flight (How Things Fly Demonstration) Work?

Flying is like being pushed and pulled by four invisible helpers that work together to make a plane go up, down, and all around.

Lift is like when you jump on a trampoline, it pushes you up! On a plane, the wings are shaped so air moves faster over the top than under the bottom. This makes the air push the wings upward, lifting the whole plane into the sky.

Weight is just how heavy something is, like your backpack full of toys. The heavier the plane, the more lift it needs to stay up in the air.

Thrust is like when you pedal really fast on a bike, it makes you go forward! On a plane, engines give thrust by pushing air backward, which makes the plane move forward.

Drag is like when you stick your hand out of a moving car window, it pulls back on you. On a plane, drag is the air fighting against the plane as it moves forward. The plane has to work harder to keep going if there’s more drag.

Together, these four helpers, lift, weight, thrust, and drag, make flying happen!
