I cannot believe that any qualified teacher or university professor

Yours wasn't
Dawlish by an chance? OK the centrifugal force is not a force field
like gravity, magnetism, etc., but the centrifugal force can be
calculated, see your link which describe it
http://scienceworld.wolfram.com/phys...ugalForce.html . That
link is proof enough for me. Strange that one can get so many hits
for centrifugal force if it does not exist.

You can get many hits for chemtrails but that doesn't make them any
more real than centrifugal force.

By the way, if you do release the centripetal force, e.g. a hammer at
the Olympics games, then it will fly off, just as you predict if the
centrifugal force did exist.

The hammer flies off because the force is removed, there is no need to
invent another force to explain it.

Correct.
