If the windmill wouldn't swivel with the windflow, it would stop, then turn into the opposite direction :-) But fortunately wind usually not changes its direction of flow 180 degrees suddenly, so the windmill can swivel ... and continue running. Wind energy generators, which usually run autonomously, also adjust the pitch of the blades according to wind speed. Above a certain top wind speed, usually 25 m/s , they shut down, regardless of direction of flow.
Yes, it gives you a push. World records must take into account the wind speed.
lines of latitude run from east to west. the most common example is the equator
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
The wind chill can run from -5 to -10 degrees fahronheit.

its heading strait for us...run!
If It's a head wind it slows down the vehicle's acceleration, lowers the vehicles top speed. If its a tail wind it could raise a vehicles top speed, that is why records have to be run in both directions to negate the wind's influence.
usually an wind turbine consists of large gears at its shaft point which produces slow speed to high speed to run the generator coupled to it
Yes, it gives you a push. World records must take into account the wind speed.
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.

The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made.

Wind
The speed in which you make your person go depends on how far you are pushing the direction stick.
