What are some words that describe skydiving?

temerarious



Nice word! I've used this word in this context before, too.

Here's my contribution: venturesome, bold, exceptional, giddy, rush

L=((((1/2)rho)V^2)Cl)A



You know, I almost got that embroidered on the side of my rig, as a kind of a subtle little reminder.

Then I decided that it was too geeky for words. :)



I truly do want to know what that equation says. Please interpret.
I like coconuts. You can break them open and they smell like ladies lying in the sun!

Sure. It's the classical lift equation. It says that the lift (L) is one-half the air density (rho) times the velocity (V) squared times the lift coefficient (Cl -- more on this later) times the area of the wing (A).

The lift coefficient is a way to collapse a lot of complex aerodynamical interdependencies (like wing shape, the viscosity of the air, air compressibility, etc.) into one nice variable. For given air conditions and an object, we have to determine a value for Cl: for simple situations this can be done mathematically but in general this is determined by experimentation.

As an aside, one-half the air density times the velocity squared has a special name (dynamic pressure) and is used elsewhere (Bernoulli's equation comes immediately to mind).

Hope that helps. :)
