In physics, this effect is called conservation of momentum. The vector sum of the resulting momentums of the struck near-frozen stones and the thrown rock must equal the momentum vector of the thrown stone just prior to impact.
The red stone you throw rotates counterclockwise. The blue stone hit rotates clockwise, the same as the 2nd red stone. The 2nd blue stone rotates counterclockwise. Am I right? But I don't understand the behaviour of the 2nd red stone: shouldn't rotate in the opposite direction? (Sorry, english is not my first language)
Thank you for your reply. As someone who has played a bit of billiards, I struggle to understand why curling stones don't behave exactly like billiard balls. I suppose the fact that curling stones are usually rotating (which you mentioned), plus the difference in material, plus the ice all contribute to making curling significantly different from billiards. Thanks again. Also, I have watched the famous RUclips video, "Curling Rock Drag Effect at the Moncton 100". I guess if Ed Werenich can be fooled, I can be fooled too. :D
I've seen that before... Good clip. That's interesting about billiards. I don't know much about billiards, but you're probably correct about the material, surface, etc.. It could also be the shape of the stones as well. Curling stones are cylindrical whereas billiard balls are spherical. I have no idea if that matters, just an observation.
for drag effect specifically, the sticking bands on the rocks literally "drag" each other when struck closely together like this, so old worn down striking bands tend to need the rocks closer together for the drag effect to occur than brand new rocks do.
It's more of a continuum rather than a defined 2 inches. As you get further and further out from 2 stones touching, the effect gets smaller and smaller and it's really not noticeable after a few inches. There's a drag effect from 10 feet out, but it's not noticeable. :)
Thank you so much for all of these game improving classes ❤️
Thank you so much for the nice comment!
Thanks for the tip
Very cool. I'm the guy who would have hit the other side of the blue stone, but not anymore. Thanks.
We were all once that guy (or gal) :)

@@CurlingClass it certainly matters

So the drag effect is how to get the frozen stone to shantee and stay, and the back stone to sashay away.
But WHY does the drag effect not happen if the stones are two inches (or more) apart???

Stone Stone Stone Stone Stone... the people take this very serious. This is just stupid.
We apologize for forcing you to watch this video.
