How do you find terminal velocity?

[yoyopizza]

So I have a limited knowledge of physics, and so every article i have attempted to read contains to much technical jargon for me to understand. Can you please explain how, if given say a sphere, what measurements would need to be known? How would I go about calculating terminal velocity? Also with any equation please state what each variable actually stands for. Thanks!

How would I go about calculating terminal velocity?

The terminal velocity is usually zero. When a person is dead and buried he can be considered to be at rest with respect to the Earth.

Seriously, I'd try http://hyperphysics.phy-astr.gsu.edu/hbase/airfri2.html
and http://en.wikipedia.org/wiki/Terminal_velocity.

The zero velocity thing was of course a joke.

I figured it was, even I know that terminal velocity isn't zero.
