What is Lift?
Upward force created by an airfoil when it is moved through the air.
What is the upward force created by an airfoil when it is moved through the air called?
Lift
What is an Airfoil?
Any surface designed to obtain reaction such as lift from the air through which it moves.
What is a surface designed to obtain reaction from the air called?

What is the Angle of Attack?
The acute angle formed between the chord line of an airfoil and the direction of the air striking it.
What is the term for the acute angle formed between the chord line of an airfoil and the direction of the air striking it?
The Angle of Attack.
What is the Chord Line?
An Imaginary straight line joining the leading and trailing edges of an airfoil, where the end points represent the maximum radius/length.
What is the term for the imaginary straight line joining the leading the trailing edges of an airfoil?
The Chord Line.
What is the Camber?

What is Bernoulli’s Principle?
At points where the speed of a fluid (liquid or gas) increases, its internal pressure decreases.
What principle states that at points where the speed of a liquid or gas increases, its internal pressure decreases?

What is Newton’s Third Law of Motion?
For every action, there is an equal and opposite reaction.
