Properties of air
The property that can take up the area with air.
How can air take up space?
True or false: Bernoulli's principle explains how the wings of flying animals keep them in the air.
What is true?
it pulls the flying object down due to gravity
Weight
In order for birds/planes to move forwards.
What is propulsion?
The study of moving air
Aerodynamics ???
This property can prove that you can weigh air.
Air has mass ???
The wings of birds that are curved more on the top than bottom
What is airfoil?
Is it Thrust
The reason why vehicles rust and food expires.
What is oxidation
An educated guess.
Hypothesis?
The property causes air to be able to squeeze into smaller spaces.
Air is compressed ?
This states that energy is conserved in a moving fluid (liquid or gas)
What is Bernoulli's Principle?
A force that pushes up on an airplane.
What is Lift
This means "The process of burning"
Define Combustion.
The best visual example for aerodynamics.
birds, planes, helicopters, airfoll
It proves that air pressure can affect the outside and inside of our bodies.
Air is affected by altitude?
What does bernoulli's principle state?
This principle states that The faster the flow of air, the lower the pressure and the slower the flow of air, there is more pressure.
If lift becomes greater than weight, the plane ______.
Does it ascend ?
What is the pushing of air against an object?
Air resistance.
in other words it means air.
Another word for Atmosphere?
If this property is unbalanced, it can either: cause the object to collapse or shatter.
Can air exert pressure ?
Bonus: This person made Bernoulli's principle.
Who is Daniel Bernoulli?
This force requires friction which causes it to slow down
What causes Drag?
There needs to be a balance between these in order to hover.
The forces of flight (drag, thrust, lift, weight/gravity)?
A factor that can be changed o measured.
What is a variable
