Actually thrust is aerodynamically involved, its the driving force that accelerates the aircrafts in forward direction and the opposite force is drag. The opposing force against gravity in a flight is lift.
Lift is the upward force that opposes the force of gravity.
Any force with an upward vertical component does.
Buoyancy is an upward thrust or force exerted by a fluid , that opposes an object's weight.
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.
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
Buoyancy is an upward acting force. It is caused by fluid preassure which opposes an objects weight ( their gravitational pull downwards ).
Drag
No. We call the upward component of force "lift"."Thrust" is the component of force forward ... the direction the plane's nose points.
Thrust is the forward motion of the airplane provided by the engines. Lift is the upward force on an airplanes wing.
The 4 main forces of flight are: drag, thrust, lift and weight
Lift opposes gravity and drag opposes thrust. An airplane turns using a small amount of vertical lift vectored in a horizontal direction. gravity from below, the wind currents, atmospheric pressure and weight of the plane from above.
