Re: Loaded dice



No matter what, angular and linear momentum is
conserved. (Remember last year's list discussion about
a diver?) But with high velocity objects, aerodynamic
forces introduce lots of complexity. With little or no
angular momentum for stability, any small unbalanced
force would produce a torque and perhaps sytart a
tumble.

But let's stick with a (low velocity) die. While it's
in the air, it will retain whatever momentum it left
the hand with. Only when it contacts the table is it
possible for an external force to produce a net torque
(I think). It would be interesting to see a video clip
of fair and unfair dice as they tumble and roll across
a table. John Barrere

They have a loaded end, somewhat aft of the center
point, by all
accounts.

It seems to me the effect of the "loaded" side only

not while the die is in the air) and the die is
more
likely to lie heavy side down. John BArrere

How do you drop anything in free space?
