Answer The essence of your question is very complicated and concerns fluid mechanics but I will simplify it as much as possible. In short, the force that opposes lift is weight (the gravitational force acting on an object's mass). If lift is greater than weight leaving all other variables such as air resistance are left the same the object is ascend. If weight is greater than lift the object will descend if already in the air or never take off if still on the ground. This question is at the heart of why planes fly. The leading edge of the wing causes the air on top to travel than the air on the bottom. Bernoulli's principle says as the speed of a fluid increases the pressure of the fluid decreases. As a result, the air on top of the wing has a lower pressure than the air on the bottom. Fluid go from high to low pressure. The air on the bottom of the wing exerts a force upward and thus the plane rises. It is important to know the other two force crucial in the flying of plane. They are thrust and drag. Thrust is the reactionary force to the force that push air out of a jet engine or from propellers. Drag is the force of air resistance and it is proportional to the velocity of the object. In other words, as the object goes faster the force trying to slow it down increases as well. This continues until the object reaches terminal velocity. Terminal velocity is the point at which the force acting on an object and the frictional force become equal in magnitude and opposite in direction. As a result, the net force acting on the object is zero and the object stops accelerating and falls at a constant rate from that point on.

What is the upward force due to fluid flow around an airplane wing?
Dont know maybe density force.
Force that opposes motion of surface as it moves across another surface?
the force that opposes the motion of two touching surfaces is velocity.
When you lift a box off the ground gravity opposes your lifting force?
It's because you can't create a force with your muscles that exceeds the forces of gravity attracting the box and the Earth toward each other.
The force of gravity opposes what other force?
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
What opposes motion between surfaces that are touching?
Force of friction
What fluid opposes lift?
Parasitic drag is a fluid force that opposes lift. It is caused by the friction and resistance of the air against the surface of the aircraft, slowing it down and requiring more power to maintain lift.
What fluid force of opposes lift?
The fluid force that opposes lift is drag. Drag is the force that acts opposite to the direction of an object's motion through a fluid, such as air. It acts to slow down the object's movement, including an aircraft's forward motion.
What is the force that opposes lift?
The force that opposes lift is drag. Drag is the aerodynamic force that acts opposite to the direction of motion of an object moving through a fluid (such as air). It is caused by air resistance and friction as the object moves through the air.
What force opposes lift?
Drag
Is the upward force that opposes the force of gravity?
Lift is the upward force that opposes the force of gravity.
Which force in fluids opposes motion?
Such force is called viscosity..the force produces in liquid and opposes the motion of fluid and also the motion of the objects in fluid..it is also called the internal friction..
What force opposes motion through a fluid?
Fluid friction, also known as drag force, opposes the motion of an object through a fluid such as air or water. This force arises due to the interaction between the moving object and the fluid particles.
What is a fluid force that opposes motion?
It is known as viscous drag
What force opposes motion in fluids?
Viscosity is the force that opposes motion in fluids. It is a measure of a fluid's resistance to flow, and it arises due to internal friction between the molecules within the fluid.
Hen you lift a box off the ground gravity opposes your lifting force?
This is true
Is fluid friction a force that opposes the motion of an object through a fluid such as water?
Yes, fluid friction is a force that opposes the motion of an object through a fluid like water. It occurs due to the interaction between the object and the fluid molecules, which creates resistance that slows down the object's movement.
Why does a buoyant force act on every object in Fluid?
Buoyant force is defined as the upward force exerted by a liquid, gas or other fluid, that opposes the weight of an immersed object. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid displaced by the objects. Because all of the objects displace the fluid, buoyant force acts on all of them.
