as an external force lift is made by a low pressure system on the underneath of the air foil. also it is possible to creat compression on the tip of the air foil.
Drag forces are contact forces, as they act between a solid object and a fluid (such as air or water) that it moves through. The drag force arises due to the interaction between the object and the fluid surrounding it.
There are many forces that could act on an object, depending on the situation. An object moving on a surface is likely to slow down due to friction, which is related to the gravitational force. Air resistance will affect objects to slow them down, which is proportional to the speed their travelling at.
The aerodynamic forces acting upon a glider in flight are lift and drag. Lift is generated by the airfoil shape of the wings and acts in an upward direction to support the weight of the glider. Drag opposes the motion of the glider and is caused by air resistance.
The main forces acting on a hovercraft are lift, propulsion, and drag. Lift is generated by the cushion of air under the hovercraft, propulsion is produced by the engines to move the hovercraft forward, and drag is the resistance encountered as the hovercraft moves through the air or water.
The main forces that act against a rocket are air resistance (drag) and gravity. Air resistance causes drag as the rocket moves through the atmosphere, which can slow it down. Gravity pulls the rocket back towards the Earth, requiring the rocket's engines to generate enough thrust to overcome it and achieve liftoff.
The pair of opposing forces that act on water moving down through the soil are gravity pulling the water downwards and capillary action which moves water upwards against gravity due to adhesion and cohesion forces in the soil pores.
Capillary action and gravity is a a pair of opposing forces that act on water as it goes down through the soil.
Drag forces are contact forces, as they act between a solid object and a fluid (such as air or water) that it moves through. The drag force arises due to the interaction between the object and the fluid surrounding it.

When a shard is submerged in a fluid, such as water, several forces act on it. The main forces include buoyancy, which is an upward force exerted by the fluid on the shard, and gravity, which is a downward force pulling the shard towards the center of the Earth. Additionally, there may be drag forces acting on the shard as it moves through the fluid, resisting its motion. These forces collectively determine the shard's behavior and movement in the fluid.

Birds have hollow bones, making them lighter. Also, the wing is the shape of an airfoil. And the bird must get enough lift and thrust to overcome gravity and drag. These are the four forces that act on any flying thing.
it moves with uniform velocity ... constant speed in a straight line
