What term creates the lift that allows gliders to fly?
unequal pressure
What creates the lift that allows gliders to fly?
Unequal Pressure The aircraft's wing is shaped so that the air passing over the wing moves faster than the air under the wing causing a positive pressure differential, thus creating lift. In simpler terms, it is the air moving above the wing, not below the wing, that causes lift.
How do aeroplanes fly even though there airfoils cant flap like birds wings?
The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.The different air pressure above and below the wings creates lift and allows the 'plane to fly given enough forward motion.
Why is weather forecast important for hang gliders?
Hang gliders rely on currents of warm air called thermals - to lift them high into the atmosphere. Knowing the type of weather in the area they want to fly - enables them to plan a route to make the most of the available updrafts.
What does airplane swing contribute to the lifting force force on an airplane?
When the wing is straight it creates more 'lift' . When swept it allows more speed.
The main rotor on a helicopter creates what?
the main rotor creates lift.
What causes awing to lift?
The aerofoil shape of a wing is designed so that the speed of air flowing above the wing is faster than that below. This creates an upward force, called lift.
How does an airplane achieve lift?
The speed of air over and under the wings creates pressure which is lift.
What does the oxidation of hair color do?
When using a permanent hair color, the mixing of two chemicals, peroxide and ammonia with oxygen, creates a chemical reaction called oxidation. Oxidation opens up the cuticle layer of the hair which allows the hair color to lift and deposit color into the hair.
How do planes glide?
The same way it flies... Gliders are lighter and they use Bernoulli's principle for lift. and once they get speed they can keep flying... they also use updrafts from the ground to get lift
An airplane stays in the air because the air pressure on the top of the wing is less than the pressure on the bottom This creates a phenomenon called what?
Horseisle Answer : Lift
What is the name for the convection currents used by glider pilots to gain height?
They are called THERMALS. Check out http://www.gliding.co.uk/whatisgliding/soaring.htm for detailed information about these and other sources of lift used in soaring sailplanes (gliders).
