wrote: "Wind drag" slows down the gravity acceleration? Fancy. Wow. There goes any credibility you purported to have with your Newtonian physics talk. Obviously wind drag doesn't affect gravity's pull...But are you really suggesting that there is no NET loss in speed down the slope when wind drag is increased ? Sorry, IS but you've really dug yourself into a pretty deep hole with this thread. |

"Wind drag" slows down the gravity acceleration? Fancy. Wind drag doesn't "slow down" "gravity acceleration", because there is no such thing. There is force exerted by gravity and in the absence of any opposing force it accelerates objects at the same rate: 9.8m/s/s. But there are a couple of opposing forces. The friction of skis on snow, and as you gain speed, drag due to moving through the air creates an opposing force; resulting in a maximum velocity being reached where the snow friction and air drag precisely equals the component of gravity that is in the direction of the slope. And now you finally know one small fact about skiing. Try tucking to enjoy a fall line schuss. Also try a steeper slope. That would be a different run, wouldn't it? http://www.youtube.com/watch?v=w1wwq35gZlg Once again, there are no moguls in that run. -- "The iPhone doesn't have a speaker phone" -- "I checked very carefully" -- "I checked Apple's web pages" -- Edwin on the iPhone "It is Mac OS X, not BSD.' -- 'From Mac OS to BSD Unix." -- "It's BSD Unix with Apple's APIs and GUI on top of it' -- 'nothing but BSD Unix' (Edwin on Mac OS X) '[The IBM PC] could boot multiple OS, such as DOS, C/PM, GEM, etc.' -- 'I claimed nothing about GEM other than it was available software for the IBM PC.

(Edwin on Sun)- Hide quoted text - - Show quoted text - And since the force of gravity is almost always nearly vertical, and the drag force is directed in opposition to velocity, the vector sum of those forces (plus the "normal force" or resistance of the surface to being penetrated) sum to the resultinmg accelerating force. |

Richard, thinking about it...this is probably something that could be calculated. All we need is an average mass of poles...IS's weight...and a good estimate of the snow surface coefficient of friction. Since IS like to dabble (to my amusement) in physics, maybe we could crunch the numbers for him...then watch him squirm away from the undeniable reality...Should be fun. |

http://www.youtube.com/watch?v=gnmTyN0VX5o Hey, that looks like the bike path from Squaw to Tahoe City along the Truckee River! I know that path - it follows the old railroad right of way from back in the 1930s. You be careful out there - I was biking along that very same path and some idiot in his car on the road above lost control, came off the road crossing the path perpendicularly and knocking the woman biker directly in front of me into the air and down into the river; his car also landed in the river, upright. I check on the woman - no immediate life threat, breathing, not drowning (shallow water), no bleeding, coherent; so I made a quick check on the driver. Sitting in his car in the river, comfortable, and talking on his phone with his lawyer. Asshole. He never did check on the woman he hit. So stay alert - it may seem you're away from traffic, but traffic can come out and get you. |

hey asshole ,
take a few lessons in skiing and photography !!!!!!! Dick "taichiskiing" wrote in message ... On Jul 4, 6:13 am, "D." wrote: you call yourself a cameraman . i hope you can do better than that " piece of **** " video . Dick No, I call myself a skier. It is a ski forum, do you ski? Are you lost? Or just lost your mind? IS "taichiskiing" wrote in message ... Interesting moment caught on tape; see the spinning camera shot toward the end of the clip, http://www.youtube.com/watch?v=UreDL2Zshvw As a cameraman, I suppose to keep the lead skier in the picture, and when I formation ski with someone as a "wingman," I usually duplicate the lead skier's every move, so, when he spun I followed suit and not realizing I was holding the camera.

Well he does that on skis too, and calls THAT something different, so it fits the pattern. |

"Mind thinks, body moves," total body automation. Gapper troll, IS So....why are the guys in this forum so nasty? Anyway, that is a cool example of big time muscle memory. And yes you are an amatuer cameraman, but that makes it all the more difficult to video a skier when you don't have stabilizing outriggers, cushioned eyepieces and all the goodies that Warren Miller camera guys get to use! gr |

In article , taichiskiing wrote: Fancy little fact, so what makes you think that the outstretched arms slowdown more than skiers holding their poles? Yes, absolutely. Look up "drag coefficient" and "area". You forgot the torque/de-stability generated by swinging those poles around. That would be a different run, wouldn't it? http://www.youtube.com/watch?v=w1wwq35gZlg Once again, there are no moguls in that run. Once again, you ain't got no talent to see it. I can see the tops of your boots at all times. Hence: no moguls. Your narrow-minded definition doesn't shed the light on this subject. You get stuck on the *sizes* of the "moguls" and missed the *techniques* of "mogul skiing." Taichi Skiing/line-skiing tends to shrink the size of the moguls as it rides the equal equilibrium-line through the moguls. IS -- |
