How does airflow over wings contribute to the lift generated by an aircraft?
Airflow over wings creates a pressure difference, with faster air on top and slower air on the bottom. This pressure difference generates lift by pushing the wing upward.
How do wings work?
Wings work by generating lift through the Bernoulli principle and Newton's third law of motion. When air flows over the wing, it creates a pressure difference which results in lift. The shape of the wing, along with its angle of attack, plays a crucial role in generating lift and controlling the movement of the aircraft.
2. What are three major factors that can change the velocity and pressure of air flow around a wing and thus increase the amount of lift?
Angle of attack: Increasing the angle of attack of the wing can increase lift by creating more lift-producing airflow over the wing. Airspeed: Higher airspeed results in increased flow velocity over the wing, generating more lift. Aircraft weight: Lighter aircraft require less lift, while heavier aircraft need more lift, influencing the pressure and airflow around the wing.
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
How does a helicopter achieve lift?
A helicopter achieves lift through its main rotor blades, which spin rapidly to create lift by generating airflow over the rotor blades. The shape of the rotor blades and the angle of attack can be adjusted to control the lift produced. This lift overcomes gravity, allowing the helicopter to become airborne.

How do rotating rotors contribute to the functionality of a helicopter?
Rotating rotors on a helicopter create lift by generating airflow over the blades, allowing the helicopter to take off, hover, and maneuver in different directions.
Is lift produced by the angle of attack?
Yes, lift is primarily produced by the angle of attack, which is the angle between the wing's chord line and the oncoming airflow. As the angle of attack increases, the airflow over the wing changes, creating a pressure difference between the upper and lower surfaces, which generates lift. However, if the angle of attack becomes too high, it can lead to stall, where lift decreases sharply. Thus, maintaining an optimal angle of attack is crucial for effective lift generation.
What is affected by an airplane's speed?
Airflow ans lift over the airframe is affected by the airplane's speed.
Why does a glider produce more lift the faster it goes?
A glider produces more lift at higher speeds due to the increased airflow over its wings, which enhances the generation of lift according to Bernoulli's principle and Newton's third law of motion. As the glider accelerates, the difference in air pressure above and below the wings becomes greater, resulting in increased lift. Additionally, faster speeds reduce the angle of attack required to maintain level flight, allowing for optimal lift without stalling. Thus, the combination of increased airflow and efficient wing performance leads to greater lift production at higher speeds.

Why airplane moves forward to fly why not helicopter do like that?
Because the airplane must have airflow over it's wings to get lift. Helicp[ters get lift from the main rotor turning

Why a paper airplane that is aimed towards the sky will return to the ground?
a paper airplane will run out of momentum, momentum (speed, vertical speed is required for the airflow over the wings to generate lift, a too high angle of attack (nose high) will cause disrupt airflow over the wings and the plane will stall
How does a helicopter achieve lift?

The shape of the rotor blades and the angle of attack can be adjusted to control the lift produced. This lift overcomes gravity, allowing the helicopter to become airborne.
What causes an aircraft to stall?
The stalling of an aircraft wing is caused by the disruption of the airflow on the upper and lower surfaces of the wing, An airflow is travelling fast enough over a wing. A low pressure area develops on the underside of the wing and a very high pressure on the upper surface of the wing ......This is what causes lift- the force that allows the aircraft to fly. If this airflow is Broken or reaches a speed too slow to maintain the low pressure required to create the lift. The wing will stall
