- I'm not sure what you are disagreeing with here. In the universe
- where I live, an object on an inclined plane will undergo acceleration
- that depends on the angle of the plane with respect to gravity. If
- the opposing forces are equal, the greater acceleration experienced on
- a steeper slope will result in higher velocity.
-
- The key words in my earlier statement are "as easily." If you try to
- ski a very steep slope at very low speeds, you must expend energy to
- apply more frictional force to reduce the acceleration. This is not
- "as easy" as expending no energy to fight the acceleration, and simply
- going the natural speed of the slope.
-
- Controlling the speed is really one and only issue in free style skiing,
- because the alternative is to shuss down, and nobody seems to be doing
- it. (in racing, it also involves skiing around some arbitrary arrangement of
- objects). For some mysterious reason we have decided that the proper
- way to control speed is to carve the turns on long skis, although
- I can easily prove that this is not necessarily true, since I can snowplow
- and scrape down ANY slope, no matter how steep and mogully (I've tested
- the technique on few occasions in Verbier and Aspen , and let me assure
- you - it works just fine).
-
- Some may argue that grace is also at stakes in free style, and it was in fact
- mentioned in the original posting : well, notion of what is graceful and
- what is not comes and goes. Skiing style of the 60's champs is barely
- graceful by todays standards.
-
- You're right. Even if you slide down the slope on your back with your
- skis in the air, I should not dare to say that you are skiing
- improperly. After, all skiing is an evolving art.
-
- I (perhaps mistakenly) thought that we were interested in making
- smooth, balanced, cleanly carved turns, rather than scraping down the
- hill sideways. I also assumed that efficiency was an admirable goal.
- Even with these assumptions in place, I'll admit that there is still
- plenty of room for stylistic variation.
