CUGC Gliding Theory videos teach you everything you need to know to learn to fly gliders. The video cosvers the difference between Ground Speed & Airspeed
This slightly helped, but I still don't understand that if there is a headwind for an example, that the airspeed stays the same but the ground speed decreases. I mean if there was a headwind of 10 knots wouldn't the whole dang glider slow down by 10 knots meaning it's airspeed would change? I don't understand. So if there was a headwind of 10 knots pushing against the glider, would the speed of the glider traveling through the air actually change? It seems to me it would.
No it wouldn't. This confused me too initially. But Airspeed is really speed of the glider relative to the air. So when, in your comment, you say "wouldn't the whole dang glider slow down by 10 knots", you are intuitively yet incorrectly thinking of glider's motion relation to you, who is on the ground looking at the glider as it gets slowed down from the headwind. But from the perspective of the air molecules that are going at -10 knots w.r.t to you, the glider really is going 50 knots. hence, airspeed=50 knots regardless of headwind or tailwind.
CUGC Gliding Theory Is this an okay/true way to think of it? The airspeed is how fast you should be going if there was no wind, or how fast you are going if there is no wind, and the groundspeed is how fast you're going after the wind's effect, if any, on the glider or airplane has been added to the airspeed to find the true, actual speed of the aircraft.
I think your confusion is caused becuase the speeds are measured reative to two different things. Air speed is realtive to the air (and would exist even if there was no ground) ground speed is relative to the ground.
