Long before the Wright brothers guided their fixed-wing aircraft over the North Carolina dunes, daredevils and engineers worked to decode the secrets of sustained heavier-than-air human flight. What do you know about the physics of flight?
Which of the following is NOT a force acting on airplanes?
What part of an airplane is responsible for creating thrust?
Which force acts in the opposite direction of thrust?
What part of an airplane is responsible for creating lift?
What's the scientific name for a wing?
Which well-known scientific principle describing the pressure of moving fluids is often invoked when discussing how an airplane generates lift?
What controversial book, first published in 2001, rejects the conventional wisdom about airplane wings and lift?
"Wright and Wrong"
A different, more modern view of airplane flight relies on another famous scientific principle. Which one?
Darwin's theory of natural selection
Einstein's theory of relativity
Newton's third law of motion
When air flows over an airplane wing, it sticks to the surface. What’s the name of this process?
What term describes the degree to which an airfoil is curved?
What are the two main types of drag?
king and queen
light and heavy
parasitic and induced
This term sounds threatening, but it merely describes the position of the wing relative to airflow.
angle of attack
What's the relationship between the angle of attack and lift?
As the angle of attack increases, lift decreases.
As the angle of attack increases, lift increases.
There's no relationship between angle of attack and lift.
What happens when a plane reaches the critical angle of attack?
What part of an airplane controls pitching (tilting the nose up or down)?
What part of an airplane controls rolling?
What part of an airplane controls yawing (turning the nose left or right)?
Turning an airplane smoothly requires a pilot to operate two controls simultaneously. Which ones?
ailerons and rudder
elevators and rudder
throttle and elevators
Supersonic flight changes aerodynamics drastically. Which two forces are affected most?
lift and drag
thrust and lift
weight and drag
What number can be determined by dividing the speed of an aircraft by the speed of sound in air?
