Fluid friction acting on an object moving throught the air?
Fluid friction acting on an object moving through the air is called air.
When an object moves through a fluid?
drag or air resistance
When an object is moving faster through a fluid -how does this affect the force of friction?
In a fluid, the force of friction tends to increase when the speed increases. The exact relationship, however, is far from simple.
What is the force on an object by a fluid when the fluid is not moving?
If the object is floating on the surface of the fluid, like a boat, then the fluid is exerting the normal force on the object. The normal force is a force that is equal and opposite to the force of gravity acting on an object. If the object is under the water then the weight of the water above the object is pushing down on it.
What is an airfoil?
an object shaped to produce lift by the bernoulli principle when moving in a fluid
Fluid friction acting on an object moving throught the air?
Fluid friction acting on an object moving through the air is called air.
Do wings produce parasitic drag?
Yes. Any solid object moving through a fluid does.
What is drag and how is it related to velocity?
Drag is the force exerted by a fluid stream on any obstacle in its path or felt by an object moving through a fluid.
When an object moves through a fluid?
drag or air resistance

What is the formula for air resistance please state what each symbol or letter stands for?
Fair = -0.5pv2ACdV Keep in mind that the p is the greek symbol for density, and V has a circumflex (^) over it. I cant add greek letters to this box. This is negative because I assume that the direction the object is moving is the positive direction. Air resistance acts in the opposite direction. p - density of fluid (fluid is what the object is moving through whether it be liquid or atmosphere) v - velocity of object as it moves through fluid A - area of object Cd - Drag coefficient V - unit vector as indicative of direction object is moving in
What is a wake in fluid dynamics?
a wake ( in fluid dynamics) is the area of turbulence formed at the rear end of a moving object in fluid ( say, air or water) a wake ( in fluid dynamics) is the area of turbulence formed at the rear end of a moving object in fluid ( say, air or water)
What is an example of fluid friction?
example of fluid friction are air resistance or drag because an object moving through air actually collides with miniature particles, specially dust particles .
How does friction affect the the motion of objects?
Friction is a force that occurs when two surfaces slide past another. The force of friction opposes the motion of an object, causing moving objects losing energy and slow down. When objects move through a fluid, such as air of water, the fluid exerts a frictional force on a moving object.

What are fluid frictions?
Fluid friction occurs when a solid object moves through a fluid.
Force that act on object that are not moving?
Static friction is the force that acts on an object that is not moving. Other kinds of friction include fluid friction and rolling friction.
