What make a plane fly?

Answer 1

The first thing that makes an airplane fly is air or aerodynamics, but simply its because the thin shape of a paper airplane makes it cut through the air, along with the air's resistance, which hardly effects it.

Secondly, drag and gravity. Drag means how much air is pushed by the movement of of the plane. Gravity is the pull downward toward the middle of the Earth, the less weight the effects your plane.

Next is thrust and lift. Thrust is the forward force of the paper plane. At first, you give it thrust by using your muscles on your arm to launch the plane. After that the plane depends on converting altitude into forward motion, or gliding.

Lift is when the air below the wing is pushing upward harder than the air above it, is pushing down. The difference in pressure is what makes the plane fly. The faster the air moves over the surface of the plane, the less pressure there is.

Combining and balance all these forces for long paper airplane flights.
