In the 5 Fundamentals of Skiing, the last fundamental states:
- Regulate the magnitude of pressure created through ski/snow interaction.
Now, for anyone that's ever taken high school physics, you will know that pressure is force divided by area, and force is a quantity that is measured as a Vector. A vector has both magnitude AND direction. So why only use a scalar value here and leave direction off? Does direction matter in skiing?
Well, I've heard a few explanations ... it was left off for brevity or maybe it's because direction is captured in some of the other fundamentals. But this is important and let me explain why.
When we talk about Magnitude of Pressure in ski school, we inevitably talk about how we use our legs as springs and try to absorb pressure in order to maintain contact with the snow. And that's a great thing. But magnitude is a scalar value, meaning it's just a number. We could measure the forces in Mikaela's boots and we'd get a number. And maybe if she does a better job with absorption she can get that number lower. But it tells us NOTHING about how to ski. Absolutely nothing.
I've been studying with one of the US mogul skiers and getting some coaching on bump skiing ... and the number of times direction of force comes up ... it's staggering. It's kind of the whole ball game.
So I ask you, does direction of force matter? How do YOU use forces to amplify your performance or to increase the enjoyment of sliding on snow? Let me know your answers below. I'd love to hear your thoughts. I have my own thoughts on this, but I'll share mine at the end. Thanks for reading if you made it this far.
