9.1Conceptual Framework for Circular Motion
I now live fifteen minutes from Disneyland, so my friends and family in
my native Northern California think itís a little strange that Iíve never
visited the Magic Kingdom again since a childhood trip to the south. The
truth is that for me as a preschooler, Disneyland was not the Happiest Place
on Earth. My mother took me on a ride in which little cars shaped like
rocket ships circled rapidly around a central pillar. I knew I was going to
die. There was a force trying to throw me outward, and the safety features
of the ride would surely have been inadequate if I hadnít screamed the
whole time to make sure Mom would hold on to me. Afterward, she
seemed surprisingly indifferent to the extreme danger we had experienced.
