Physics of Flight

The physics of flight primarily involves four forces: lift, weight, thrust, and drag. Lift is generated when air moves faster over the airplane’s wings, creating higher pressure beneath and lifting the plane upward—thanks to Bernoulli’s principle and wing shape. Thrust, from engines, propels the aircraft forward, overcoming drag—the air resistance that slows it down. Weight, due to gravity, pulls the plane downward. For sustained, steady flight, pilots balance these forces: increasing lift and thrust while managing weight and drag. This intricate interplay enables airplanes to soar through the air efficiently and safely.
