Right.

Now we are at first base!


You go from up wind direction (takeoff is usually
up wind) to turn in the wind direction to land down wind. There's an
acceleration, it is a change in _velocity_

Wrong.

I see the problem. You don't know what velocity is. It's a VECTOR. It
changes when you turn. If you don't understand this there's not much
point talking about anything that involves physics....
