What is reached when the downward pull of gravity is equal to the upward push of air resistance?
The object would stop falling. This is what allows things to float, and what keeps planes in the air. ...
Asked in Fluid Dynamics
Can airplane be static in air?
Theoretically, yes. The force in which balances gravity and keeps the plane in air is produced by the relative speed between the air and the plane's wings. When the air is still, the plane has to move (fast!), relative to the air. If the planes is to be static, then the air has to move: really fast. However, winds of such strengths are rather unlikely concerning passanger jets and large planes. For small (model planes, etc), it is hightly possible. ...

How do airplanes see at night?
In the air there is not anything that they need to see since air traffic control keeps them from colliding with other planes. When landing the have lights on the runway and on the plane. they also have radar to keep them from colliding with other planes. From the lighter side: Airplanes can't see! ...
Why do you need paper air planes?
Paper air planes are source of fun and and interest to most kids. There are many different kinds of paper air planes that you can make. It depends on where and how that you want them to fly ...
Asked in Gravity
What keeps planes in the air if gravity pulls us down?
A plane is designed so that when it moves forward the air moving across its wings creates an upward force called lift, which counteracts the force of gravity. ...
Asked in Air Travel
How many planes are in the air?
well what kinds of planes planes like x y or planes like air planes it depends at whattimes there are more planes in the air than at day . then there are two planes x and y. you can never know how many planes there are in the sky unless every air port was shut down. witch is nearly imposible because in order to shut all of them down there would havee to ba some kind of electic moufunction with the...

Why is measuring the velocity of the wind and the pressure of the wind important?
Its important for the pilots in air planes and the designers of air planes. Please recommend me! ...
Asked in US in WW2
What are 3 air bases in Hawaii where the US had planes?
Hickam Field was the US Army largest base that held planes in Hawaii. Two additional air bases in Hawaii the US had planes included: Wheeler Army Air Field and Kaneohe Naval Air Station. ...
Asked in US Military, US Army
How many planes does the army have?
The army doesn't have any planes, only helicopters. The Air Force has all the planes. The army does not have fighter planes, but they do have transport planes. The navy has planes as well. All fixed wing aircraft that carry army service members are piloted and owned by the air force. But yes, the navy does have a variety of planes based off of aircraft carriers. ...
How does radar help air traffic controllers?
They are able to see where all the planes are. They can guide the pilots of the planes and tell them where to land and when to. They can tell them when the air is really busy, and when there is no one in the air. ...
