Forces of Flight
Understanding how things fly begins by learning about the Four Forces of Flight.
When an airplane flies, the wing is designed to provide enough Lift to overcome the airplane’s Weight, while the engine provides enough Thrust to overcome Drag and move the airplane forward. And the Thrust of a rocket engine overcomes the Weight of the object to move the rocket forward.
Increasing the weight of an aircraft affects the amount of lift needed. In turn, a larger wing would provide more lift, but that would increase the amount of drag and therefore increase the amount of thrust needed. The forces of flight are interconnected, and a change in one affects the others.
