What force is created when an object moves through a fluid like aircraft moves through air?

Either drag (air resistance) slows the aircraft down, or lift (Bernoulli's principle) raises it up. When more air goes under the wing than over it, the aircraft "wants" to move up because objects favor movement into low pressure zones.

What is archamedies principle?
Archimedes' Principle refers to the relationship between gravity and the buoyancy of an object in water. the exact wording is as follows: "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object."
What is turbulent viscocity?
Turbulent viscosity is a value which is assumed to be equal in all directions. It is the same as Eddy Viscosity This is a measure of a fluid which is being deformed by stress. The fact that it is turbulent just means it is changing so the internal friction or viscosity is changing constantly and this is why it is called turbulent. the internal friction is the friction within the object hence the term internal however this friction derives from the force of the fluid acting on the object. E.G if air is your fluid surrounding the object and the object is experiencing a change in the velocity of the air it will be exposed to a different amount of stress and will therefore have a different value for internal friction.
What is wrong with the statement Voltage flows through a circuit?
Voltage is the force that causes current to flow through a circuit. In a similar way it isn't pressure that flows through a pipe - it is the fluid flowing through a pipe due to a difference in pressure at the entry and exit of the pipe that causes the fluid to flow through, no pressure flowing through a pipe.
What does the term drag mean in flight?
Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics). The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air. The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.
Supernatant and pellet?
Supernatant is the clear fluid above a precipitate or sediment. Pellet is a small rounded object, ball, or spherical body.
When an object moves through a fluid?
drag or air resistance

What are fluid frictions?
Fluid friction occurs when a solid object moves through a fluid.
The friction that occures when an object moves through a fluid is called?
fluid friction
Is fluid friction a force that opposes the motion of an object through a fluid such as water?
Yes
If an object moves through the air what is the friction?
Fluid Friction .
Fluid friction acting on an object moving throught the air?
Fluid friction acting on an object moving through the air is called air.
What is Mach 1 and 2?
The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower). An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure). BUT In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
Why does a ball fall more slowly through viscous fluid than through water?
Viscosity is defined as a measure of the resistance to flow of a fluid. Therefor, the flow of, or the passage of an object through, a viscous fluid is resisted by the fluid.
What is friction that occurs when a solid object moves through a fluid?
Resistance.
Smoothing an object so that it will move easily through fluid?
streamlining
What is smoothing a object so that it will move easily through a fluid?
This is called streamlining.
