Re: [Phys-l] Killed by a Falling Bullet? - Myth busters.

Falling is a common term which can have a variety of definitions.  I would
say that the better term would be accelerating, which is a well defined
physics term.  Of course free fall is generally understood to be
accelerating due only to the presence of a gravitational field, so it is a
good term.  There is not much sense arguing over a common term.  Whether
free fall means falling is certainly disputable.
