How does a balsa wood glider gain lift?

A balsa wood glider gains lift primarily through its wings, which are designed with an airfoil shape. As the glider moves through the air, the wings create a difference in air pressure; the air moves faster over the curved upper surface than the flatter lower surface, resulting in lower pressure above the wing and higher pressure below. This pressure difference generates lift, allowing the glider to rise and stay aloft. Additionally, the angle of attack, or the tilt of the wings relative to the airflow, can enhance lift up to a certain point before causing drag or stalling.
