Thanks to you folks, I have found the "inertial ball" demonstration (I
think it's 2-13)
in the Video Library of Physics.
When I step through the "fast pull" the picture is blurry when the motion
is fast. Here's my theory
about this: I think I am being shown both fields of the video (i.e. an
entire frame) so half of
the lines were taken 1/60 sec after the other half, and this accounts for
the blur.
Does this make sense? I don't think the blur is caused the same way the
blur would be caused on
photographic on film.
