Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction.

What is the relationship between the amount of effort needed to lift the load and the distance of load from the fulcrum?
confusing
What lifts up object faster a big pulley or a small pulley?
both lift same speed both lift same speed
Why more lift is required when landing?
During landing, the purpose is to slow down the aircraft's ground speed as slow as you can without it stalling. You want to maintain Lift, not necessarily get more lift. At higher speeds, the aircraft has plenty of Lift. However during landing, the speed is slower and the angle of attack is increased to provide more Lift at lower speeds.
What is the lift off speed of a Boeing 747?
The lift off speed is dependant upon the weight of the aircraft. The heavier the aircraft the higher the speed. At maximum take off weight of 875,000 lbs (396,890 kgs) Vr (rotation speed) will be about 175 knots and V2 about 185 knots.
How does the direction of the lift on a plane compare with its weight as it flies at a constant speed and altitude?
lift acts upward, and weight acts downward
Whats the relationship between the distance traveled by the object and the force needed to lift the object When one changeswhat happens to the other?
ffr
Is there relationship between lift and weight?
yes there is
What is the relation between lift force and mach number in supersonic speed?
The only relationship is that the greater the velocity of Air over a Lifting Body (Wing in general), the greater the LIFT. HOWEVER, you cannot say that the reverse is true...that is, the greater the LIFT the higher the Velocity. You can change Lift by changing the Wing DESIGN. When Landing an Airliner deploys its WING FLAPS to create greater Lift at lower velocities.
Relationship between coefficient lift and coefficient drag?
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
What is the relationship between the amount of effort needed to lift the load and the distance of load from the fulcrum?
confusing
What has to happen for plains to lift?
If by plains you mean airplanes, in order for them to lift, they have to go fast enough. Lift is a function of speed. Without enough speed, there's not enough lift. When the plane reaches enough speed, the lift begins.
Does the moon have gravitational potential energy?
The gravitational potential energy doesn't actually reside in a single object, but in the relationship between two objects. Thus, there is a gravitational potential energy between Earth and Moon, or between a rock that you lift up on the Moon, and the Moon.The gravitational potential energy doesn't actually reside in a single object, but in the relationship between two objects.

What lifts up object faster a big pulley or a small pulley?
both lift same speed both lift same speed
What is the relationship between the effort and the weight of an object being lifted over a simple pulley?
the effort needed to lift an object is about the same as the weight of an object:)
How does an airplane achieve lift?
The speed of air over and under the wings creates pressure which is lift.
How do you calculate lift over speed governor tripping speed?
Use a tacometer drive the governor round with an electric drill and measure the speed the govenor trips. lift govenor speeds are factory set
What is the best shape of a car for speed?
well... if you have a longer car that is flatter it will have lift which lowers speed or it will lift off the ground.
