So What Makes an Airplane Fly?

Forces Acting on an Airplane LIFT THRUSTDRAG GRAVITY

Aerodynamic Forces  Thrust- forward driving force of a propeller, or the forward force produced by gases escaping rearward from a jet or rocket engine  Lift- the upward acting force that causes the plane to rise  Drag- the resistance force of friction produced by air and water  Gravity- downward force pulling everything to center of earth

How is Lift Generated?  First note:  Air is a fluid, so it adheres to the physical properties of all fluids  Air must be in motion Second note:  Second note:  Slow moving air creates high pressure under wing  Faster moving air creates low pressure above the wing

Control Surfaces for Maneuvering  An airplane uses control surfaces for maneuvering the airplane
