Gravity, although essential, plays a minor role in the forces I play with when skiing. The kinetic energy I derive from gravity is much more important in generating forces to take me where I want to go.
Nothing Idle about it. IMO it's fundamental.
At the level when one understands the concept of carving and the use the ski as a tool for circular travel, your kinetic energy is key to the generation of the resultant centripetal force. But that kinetic energy gets used and dissipates as you cross the fall line resulting in a return to gravitational balance while you set up to "recharge" the kinetic energy engine. I think we call that transition.
Gravity has been a good friend of mine since as long as I remember. I do recall the last time I saw her she mentioned getting snubbed by fatoldman. Something was said about not "needing" her anymore. He has really "shaped" up and met someone new. Centrifugal Force was her name if I remember correctly. A very lively, sophisticated and showy girl. I've also dated her in the past and, to be honest, she's not "all that" without her BBF Gravity. Once gravity leaves her side, she's all show and no action. The moral of the story, four hands are better than two when it comes to massaging the cerebellum.
