Multiple ______________ affects the plane's speed and direction?
How do the four forces of flight make an aircraft move?
During a flight, an airplane's weight _________________ changes as the aircraft burns fuel.
Magnitude is represented by a ________________.
Direction is represented by
The force of gravity's magnitude is how strong its pull and ________________ is toward the center of the earth.
Lift is the downward force that enables an aircraft to raise off the ground and remain in flight.
The downward pull of the gravity on the aircraft is called weight.
Lift's magnitude does not depend on which one of these factors?
The bigger the total mass is, the smaller the magnitude of the weight.
Lift pulls the airplane in a direction perpendicular to the direction the airplane is moving.
Thrust is the force that propels an aircraft forward.
Drag is the force of resistance that works against the __________ movement of an aircraft through the air.
The force applied by the air molecules onto the airplane’s surfaces is the force of ___________.
When an airplane moves through the air, the airplane pushes against the air, and the air pulls the airplane.
Thrust's magnitude depends on type of engine, ______________, and throttle setting.
Drag's magnitude does not depend on which of the following:
Thrust propels, or pushes, in the direction of motion. However, direction depends on how the engines are attached to the aircraft (perpendicular to the plane's body or on and angle).
Drag pushes _________________ the direction of the airplane's motion.
Drag is created by _______________ from the air and its resistance to the airplane's motion.
