Bernoulli's Principle
the statement that an increase in the speed of a fluid produces a decrease in pressure and a decrease in the speed produces an increase in pressure
Wind has nothing to do with how an airplane stays in the air. In actuality, an airplane flies better on calm days than on windy ones! It is the act of lift, weight, thrust and Bernoulli's principle (though this principle isn't all that true, since airplanes are able to fly upside down and a model airplane with non-airfoil shaped wings can stay in the air just fine) that determines how an airplane is able to stay in the air.
an airplane stays up in the air by the pressure above and below the wings...
There is actually more than one force that enables an airplane to stay in the air: that is lift, weight and thrust. Weight has to be less than the force of lift and thrust combined to both get the airplane into the air and keep it in the air.
up in the sky
The plural (skies) is often used to mean "locations up in the air" (the skies over Chicago) and not at the physical blue sky itself. It also refers to the fact that are innumerable appearances to the sky, which determine what you are actually seeing. Seeing clouds could mean a "cloudy sky" although the sky itself is unchanged if you go above the clouds.Generally, you would use sky and skies interchangeably, except where the physical sky as a whole is concerned, as in "I looked up at the sky" where skies would seem to indicate there was more than one.
level him up to 40
Went up to the sky
level up with max happiness
Sky Eats Airplane was created in 2005.
Everyone pick up their seats to keeps plane float.
bars that are put up in front of the engine so that nothing goes into the airplane's engine.
Sky Eats Airplane - album - was created on 2008-07-22.
what keeps planet earth from fallin out of the sky
Lift keeps an aircraft up, thrust pushes it forward.
It keeps you alive.....
yes
An auto-pilot
to fly in the open sky, and to take up a challenge that hadn't been achieved yet.
airplane
You can see them at many airports and in the sky.
