i always thought the wind factor was the same for all clubs.
oK I'm going to take a stab at this.... I apologize to physicists and pro golfers around the world in advance... :)
Yes. The longer the ball is in the air, the more it will be effected by the wind. Simple enough to understand, but why doesn't your 300 yard drive move with the wind more than your 120 yard approach shot? there are other factors to consider...
Your swing arc on your woods and longer irons are greater, because the club shafts are longer, thus your club head speed is greater, thus the distance and speed at which the ball travels is greater. So even though your 3W puts the ball in the air for an amount of time much greater than your 9i, the velocity that the ball is traveling overcomes the effect the wind has on it.
And the converse is true, you hit the ball with your PW at a much lower velocity (because of the shorter club length and arc which lessens your club head speed) Also the blade angle is more severe, causing the ball to travel at a higher trajectory, increasing airtime, and the effect of the wind on the ball, relative to the distance the ball travels.
So once you factor all that in, yes the wind will move your 3i and your 9i relatively the same way....
But when you have clubs that go the same distance, but at different trajectories, the wind will effect the ball struck with the higher trajectory club more.
You can see this for yourself, a shot with backspin will hang up in the wind a lot more that a shot with top spin from the same club.
