My first (stupid) question here: What is the "apex" of the turn? Dictionary defines apex as "highest point, vertex." Which in a ski turn on a slope would be the most uphill/highest point on slope (where skis are kinda more perpendicular to fall line) i.e., 12 o'clock in ski turn?
Compare this where apex is defined as more like 9/3 o'clock in ski turn?
"To start, I should describe what I mean by apex. The apex is
the outer most point of the arc, where your skis are pointed
directly down the fall line."
The words "outer most point of the arc" have no meaning to me, because all points on a circle are the same distance from the center. On the other hand I am good enough of a skier to know in a ski "arc where your skis are pointed directly down the fall line." And that definition of apex (seems like 9/3 o'clock) is definitely not the "highest point, vertex" (12 o'clock)
Compare Bob Barnes "Complete Encyclopedia of Skiing" where the term "apex" appears once and is not defined.
Checking for understanding: Where is this apex of turn you are talking about?
[Maybe its because I never took physics (but I did do well in geometry) so don't come here with the proper background, but without defined terms, these high level discussions which, in particular, the posters in this thread engage in (your posts are greatly appreciated BTW) are confusing to me.]
