Total questions: 10
Worksheet time: 8mins
What is lift?
The aerodynamic force that opposes weight
The aerodynamic force that opposes thrust
Air follows Newtons laws of motion.
True
False
Air has the properties of: (select all that apply)
Inertia
Pressure
Speed
photosynthesis
If air is in motion (following Newton's 1st law) what must be applied to change its motion?
Energy
Speed
A force
What is an airfoil?
The cross section of a cloud
A wing
The cross section of a wing or other lifting surface
A propeller
When an airfoil moves through the air what does it do?
It applies a force changing the direction of motion of the air resulting in lift
Creates lift to support the airplane
When air enters the restricted space of a venturi the air's speed _____ and pressure _____.
Speed: Decreases
Speed: Increases
Pressure: Rises
Pressure: Drops
How is an airfoil similar to a venturi
The upper and lower surfaces of the airfoil create a wider space
The upper surface of the airfoil has a curved surface which looks like half a venturi tube
According to Newton's 3rd Law, when an airfoil applies a force to change the motion of the air around it what must also happen?
The force causes an equal and opposite reaction
The air pressure will lower creating lift
Nothing since there was no action to cause an equal and opposite reaction
Faster moving air has ____ pressure compared to slower moving air.
Higher
Lower
