Interesting question. Lift is what actually allows an aircraft to leave the ground, but lift in a normal type aircraft (not a helicopter) is generated by forward movement through the air and that is produced by thrust. So, while lift is what's necessary to overcome gravity (weight), it's thrust that is needed to generate lift...so both forces are in play at takeoff.
Thrust is the forward motion of the airplane provided by the engines. Lift is the upward force on an airplanes wing.
No, the upward force on an airplane wing is not thrust. It is actually lift, which is generated due to the pressure difference between the top and bottom surfaces of the wing as the air flows over it. Thrust is the forward force that propels the airplane through the air.
lift, thrust, drag and weight(gravity)
"Thrust" is a force, referenced to the direction in which the aircraft is pointing. Take all the forces that act on the airplane. For each one, find the magnitude of its component in the direction in which the airplane's nose points. Their sum is the "thrust" at that moment.
The four forces acting on an airplane in flight are lift, weight (or gravity), thrust, and drag. Lift is generated by the wings and opposes the force of gravity. Thrust is produced by the engines and overcomes the force of drag, which is caused by air resistance.
Thrust is the force that provides an airplane its speed. Thrust must be brought to a certain level and maintained in order for the plane to move at a speed that is sufficient to create lift from the wings.
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.
Lift Gravity Thrust Drag Lift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down. Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down. These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.
Not, it is called lift. And trust is the power generated by the engines.
It is thrust, lift, drag and weightthat affect an aircraft's ability to fly. It is thrust that moves the aircraft forward through the air. The thrust overcomes drag and provides (with the wings) lift to overcome weight.
C. Lift. Lift is the force that acts on the airplane at a distance A while it is flying.
Without thrust, the airplane would never move forward, and without lift, it would never get off the ground. It would seem therefore, that these forces are absolutely essential to the realization of the entire notion of "airplane", since without them, it would be absurd for the pathetic craft to attempt to lay claim to the title.
