Properties of Air
Does air have mass?
YES YES YES AND YES
What is one thing that birds have that help them fly?
wings, feathers, hollow bones
What is Rusting?
Rusting involves the oxidation of iron (Fe) specifically
What is the fuselage?
The main body of an aircraft.
Who thought of newtons law
Isaac newton
What is a way that we can show that air takes up space?
Example answer: Blowing up a balloon makes the air expand the balloon.
what is something that birds have that help them fly throught the air faster?
Streamlined bodies
What is the troposphere?
It is the closest layer of the Atmosphere to Earth.
What does the engine do?
It propels the plane forwards
What is Bernoulli principle?
The speed of air determines the amount of pressure it exerts Faster air LESS pressure Slower air MORE pressure
Does air shrink when it heats up?
NO IT EXPANDS!!!
What are the parts of a feather?
barb, hooklets, barbule
What is combustion?
When a material reacts with oxygen and releases heat.
What does the "rudder" do?
It creates or changes yaw
What is the coanda effect?
flowing fluids stick to curved surfaces.
What state of matter is Air???
A gAs
How do birds steer?
using their tail
What is air made up of?
78% Nitrogen, 21% oxygen, 0.9% Argon, 0.03 carbon dioxide
What are the three movements of a plane?
Roll, pitch and yaw
How do we use Bernoulli's Principle to cause lift?
Airfoils!: a shape designed to produce lift when air flows around it a shape designed to produce lift when air flows around it
how does the speed of air impact air pressure?
Fast air (wind) reduces pressure, slow air increases air pressure.
what is the thing that some birds have in their eyes that help them with blood flow and higher heartbeat?
clear inner eyelid
Where is 99% of the water vapour in the atmosphere?
It is the Troposphere
What way do the Ailerons have to be for the plane to roll left?
the left aileron would go up and the right aileron would go down.
What are the 3 newton laws and explain them.
#1 An object at rest stays at rest and an object in motion stays in motion if an ob jectisn't moving it won't start moving without help if an object is moving it will continue to move until it is stopped #2 The acceleration change of speed of an object is related to the force applied to it if an object is pushed harder it will accelerate change speed faster applies to speeding up and slowing down #3 For every action there is an equal and opposite reaction Ex If a rocket pushes on the ground the ground will push back and launch it into the sky
