A passenger jet in the air increases its speed Does the downward force of air on the top of the wings increase or decrease Does the net lifting force of the air on the wings increase or decreasExplain?

Answer Lift on a wing increases with (a) airspeedand (b) angle of attack. However, there are several factors and limitations to this. The Angle of Attack is the angle that the wing with respect to the air flow. Increase in Angle of Attack will increase lift until you reach an angle where the wing stalls. Same with Airspeed. Each wing has a unique airfoil shape that is designed for the flight regime that is intended for the aircraft. Some airfoil shapes are designed for low speed and some for high speed or supersonic speed. So, it is hard to give a general statment about all wing designs. Also the TOP of the wing is curved more than the bottom. This requires the air flowing over the top of the wing to speed up which reduces the air pressure. Since the air pressure on top is less than the air pressure on the bottom, the wing has a net force that is UPWARD ---no downward--- and this is called Lift.

∙ 11y agoYour question is vaguely worded, but I can guess what you are trying to ask. An airplane wing is designed so that when the airplane is moving at a high speed, there will be less air pressure exerted on the upper surface of the wings, which therefore means that the air pressure exerted on the bottom of the wings will help to hold the plane up in the air. Technically, this is called the Bernoulli effect.

∙ 14y agoWith forward (or reverse) motion, the downward force on the top of the wing is less than the upward force on the bottom of the wing because the top of the wing is arced. This provides "lift" for the aircraft.

Precipitation that soaks into the ground trickles downward due to?
precipitation is the water that soaks downward due to the ground trickles
Objects that are able to fall have what type of energy?
When a body is supported at a height, it has potential energy. When it is released, it will start to fall. As the downward velocity increases, so kinetic energy increases. The potential energy is reduced as the height of the body decreases.
Why do pitcher plants have a smooth slippery surface with downward pointing hairs?
To trap insects for food. Slippery so they can not get a grip and downward pointing hairs to make climbing out difficult.
Why do you need to use force to move a ball up a ramp when it moves downward by itself?
The force of gravity makes the ball move downward. To move it upward, you need to supply enough force to compensate for this (to stop the downward motion) plus a little extra (to cause the ball to move upward).
Which of these terms can be defined as a root's downward growth as a response to gravity?
geotropism
When an object falls freely the kinetic energy of the object will?
It will decrease if the object moves upward; decrease if the object moves downward.
When you translate a figure downward does the y-coordinate of the image increase or decrease?
It decreases.
Does atmospheric pressure increase or decrease under sea level?
It increases. The lower you go, the more mass there is in the column of air (or water) above you. The earth's gravitational attraction pulls that column downward. In a fluid, the pressure is equal in all directions.
How do the horizontal components of a projectile motion vary from the vertical components?
Horizontal . . . acceleration is zero, speed is constant Vertical . . . acceleration is 'G' downward, speed constantly increases downward
The passenger side of my Lincoln mark v11 is leaning downward?
sounds like an air bag problem
Why demand curve slopes downward?
Demand curve is slope downward because of inverse relationship between price and quantity.
Explain the subsititution and income effect of decrease in price?
substitution effect is the explanation for the downward slope of the aggregate damnd curve.
When the points on a graph tend to go downward from left to right you say that they indicate?
A negative slope. a decrease, a fall, etc.
When a supplier makes a downward adjustment in the amount owed by a creditor the creditor will?
increase the amount of the account payable to the supplier, and decrease an asset such as inventory.
Where is the knee bolster in 1992 Corvette?
The knee bolster is the upholstered panel below the glove box, angled downward, away from the passenger.
If a skydiver jumps out of an airoplane how much gravity is hitting him?
Exactly the same as hits a passenger sitting comfortably in another airplane at the same altitude:A downward force called his "weight", and a downward acceleration of 9.8 meters per second2.
What happens if a piston is used to decrease the volume of a contained gas?
The volume will increase as the piston moves downward. If the cylinder is sealed and the gas can not escape, the pressure in the cylinder will decrease. If the cylinder has a small opening as in a motor, the higher pressure outside will push in air that will mix with fuel to ignite when the spark plug is fired. (Supv note: it is not possible to have negative pressure. You can have zero pressure but not a deficit.)
