Why do gliders work?

Gliders work by exploiting aerodynamic lift generated by their wings as they move through the air. When air flows over the wings, it creates a pressure difference between the upper and lower surfaces, allowing the glider to stay aloft. Their design minimizes drag and maximizes lift-to-drag ratio, enabling them to soar for extended periods without an engine. Additionally, gliders can take advantage of rising air currents, such as thermals, to gain altitude and extend their flight.
