orbital speed how is it calculated
« on: August 26, 2005, 09:13:40 PM »
 I have often seen massive series of calculations on astronomical problems
what is the basic formula for determining the orbital speed of a satelite.
assuming gravity is constant  at all distances .
anyone got a simple explanation

Unfortunately, it's not me...
But there was this feller called Newton...  :-)

if I'd been home, I could have just picked the textbook off the shelf (I can never remember exact formulae - dysgraphia)
