I spend a lot of time on airplanes. No matter how often I fly, I’m still amazed during takeoff. The physics of flight fascinates me.
The pilot pushes the throttle, the engines create thrust, the aircraft moves forward. It’s immediately met with resistance in the form of drag from the air. More throttle. More thrust. Also more drag.
Pilots continue to throttle up until the thrust sufficiently exceeds the drag. That’s the only way a plane can generate enough speed to create the lift required to get off the ground given the plane’s weight.
Thrust must exceed drag to create forward movement and the speed necessary for flight.
