Hey Bob,

Maybe I read further in the article or some of the links
than seems to
be what some here are talking about. The one factor that
it stated
could account for the difference, was the centrifugal
force, which to
me is similar to the Coriolis effect.

Take care.

Problem here, there is no such thing as centrifugal force.
Never was, is not
now and never will be................

Where did this ever start? Every mechanics book and ME
handbook on my bookshelf that I checked gives a definition
and formula for centrifugal force.

Resnick & Halliday refers to centrifugal force as a
"pseudo-force", by which they mean it's a force due to
inertial effects, not that it doesn't exist. I wonder if
this is the source of the confusion?
