The thrust is the force moving something forward. The drag is air resistance applying force in the other direction. Drag will increase when an object moves faster because it will hit more molecules (of air, water, whatever) per second. If you apply constant thrust (force) to an object in air (for example an airplane) it will accelerate until the drag is equal to the thrust at which point it stops accelerating but keeps going at the same speed.

If drag and thrust are equal a flying device will stop?
If drag and thrust are equal, a flying device will stop ACCELERATING, that is it will maintain a constant speed.From classical Newtonian physics:Force = mass x accelerationSince drag and thrust are forces, we have:Thrust - drag = mass x accelerationSince you say that drag and thrust are equal, and the mass of a flying object is some finite value, it turns out that the acceleration = 0, i.e. a constant speed
What happens if thrust is greater than drag?
The car (or plane/whatever else it is) accelerates. This means that it gains speed
How does the lift thrust drag and gravity affect a helicopter?
Lift, thrust, drag, and gravity affects all flying objects and wildlife. The blades of the helicopter provide lift, drag and thrust.
Does a hot air balloon depend on thrust or drag?
thrust and drag, because with out thrust the hot air balloon would not be able to move forward and with out drag it would not be able to stop
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the affect of thrust lift gravity and drag on a plane?
LIFT -- force provided by the wing and in perpendicular direction to the wing. In straight and level flight the lift is exactly equal to the aircraft weight. WEIGHT -- the force pulling vertically down on the airplane due to gravity. In straight and level flight this is equal to the lift. THRUST -- the force that pulls the airplane forward, provided by the propeller or jet engine. If the airplane is flying at a constant speed in level flight, this thrust is exactly equal to the drag. DRAG -- the aerodynamic force on the airplane in the opposite direction of its travel. Drag is due to skin friction, form drag (drag around wheels, struts, etc) and induced drag (produced by the wing as a side effect of lift)
What is the opposite of thrust?
Ths is a good question but the opposite of thrust is drag.
What helps an airplane overcome drag so it can thrust forward?
Aerodynamics help reduce drag so the engines can produce thrust.
What is the relationship of lift drag thrust and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
What forces are involved in achieving launch?
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
How does an airoplane fly?
it has a shape on its wing called airfoil search it up it combined forces of thrust weight drag and lift must be equal.
Is thrust greater than drag?
yes
