Re: timing data for falling objects



some time ago Carl Adler at Eastern Carolina filmed a replica of the
imagined Galileo on the leaning tower experiment. If you had a copy,
you could extract time and position data from it...of course you could
just make your own video.

cheers

Oops - Here is a more specific request: Does anyone have timing data for an
object (like a ball or human), released from rest within a kilometer of the
earth's surface, falling over several seconds (as opposed to just a second
or so)?

theory.

I suspect this isn't the desired answer, but: The
moon is undergoing free-fall, and accurate timing data
has been collected for nearly a billion seconds.

Do a search on "exterior ballistics" e.g.
