Re: [Phys-L] Falling - the tale of a simple 1st degree non-linear ODE

Ah yes: the difference between an Earth referenced 220 km altitude, and a Space Station referenced 220 km altitude. The video evidence from astronauts seems fairly conclusive. (which reminds me of the enthralling demonstration of periodic spin reversal of an object spinning on its intermediate axis of angular inertia!

I’m gonna go out on a limb here and opine that a bowling ball dropped from an altitude of 220 km is unlikely to linger in the vicinity.

Now a roadrunner walking off a 220 km high cliff ... that’s a different beast.
