Matt, I just found your videos yesterday and have already watched at least a dozen. These are great and as a new skip and relatively new curler I'm learning a lot. I didn't know there was any math behind raises and have always been going by feel. I can hardly wait to get out there this year (Covid permitting) and practice what I'm learning. Thanks and keep them coming!
Hi Ralph. I’m so glad that you’re finding them useful. I’m going to be adding more and developing the website, curlingclass.com every season over the next several years. Your comment helps to keep me motivated. Thanks again and good curling!
If you ever pick up making new videos as a newer skip I struggle to know where to put the broom for raises and would appreciate any guidance you could provide!
Well I'm no physics major but it could be for a few reasons. One being that the thrown stone doesn't hit the promoted stone directly on center so some of the thrown stone keeps a little bit of it's velocity and momentum and the energy isn't transferred to the promoted stone. Another thing I would consider is that some kenetic energy is lost when the two stones collide (I think, again, not a physics major :)) That's my best guess.
@@CurlingClass I realize this is 3 years later, but the answer is the difference between static and dynamic friction coefficients. The sitting stone uses static friction to stay put and the sliding stone uses dynamic friction to slow down. Static friction coefficients are larger than dynamic. Think about how when you're driving on snow and trying to brake. If you start sliding, your tire goes from static to dynamic friction, and stopping is less effective. That's why anti-lock braking systems pulse. It tries to engage static friction again. There is also energy loss in the collision due to deformation, noise, and heat. That is probably less of the reason here though.
The two stone description was especially helpful

I love these videos! I've learned so much! Great work!
I've just come across them and will definitely be checking them out... ...but my very first reaction was "Your scoreboards go up to 18?!"
Why is the extra energy needed? Is it because a stationary stone is set in ice and some energy is lost to get it moving?
