No it doesn't
On or near the Earth's surface, 750 kg of mass weighs 1,653.5 pounds (7,350 newtons). Any force greater than that will lift the water from the well. The greater the force, the sooner the water will reach the top.
Well, there obviously gravity and lift. But there are two more. They are drag and thrust. Gravity operates all the time. Then you give thrust to the aircraft, to create lift, and drag will automatically operate. Gravity pulls you down, lift pushes you up, drag slows you down and thrust accelerates you. Gravity and drag are both bad for launch. Lift and thrust are absolutely essential for launch. So there you have it. Gravity, Lift, Thrust, Drag
If the lift is greater than gravity then the airplane gains altitude.
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.
thrust that is greater than earth's gravity
as high as the lift from the wings is greater than the gravity pulling it down
...the same or greater than...
Greater lift
(Airplane is descending)
gravity you idiot. Become weightless, then talk.
A force greater than the weight of the load,applied to it in the upward direction, does.
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.
It takes off
Thrust . i mean a force required to overcome the gravity of earth and which is greater than its weight.
