What paper airplane is the upward force that opposes the force of gravity?

The upward force that opposes the force of gravity on a paper airplane is called lift. Lift is generated primarily by the wings of the airplane as it moves through the air, creating a difference in air pressure above and below the wings. This force allows the paper airplane to stay aloft and counteracts the downward pull of gravity. The design and angle of the wings significantly influence the amount of lift produced.
