• Landing

What do you need for an object to fly?

• Engine

• Gasoline

• Wings

• Force to Lift it

What types of force can an airfoil exert?

• Either a descending force or a force that pushes

• Either an ascending force or a force that pulls

• Either a force that pushes or pulls depending on speed

• Either a lifting force, or a force that pushes or pulls

Which edge of an airfoil cuts through the air ahead?

• Chord

• Camber

• Leading

• Trailing
