The Saga of Sally =

Once upon a time, there was a =
little girl=20
named Sally Sue.
One day, she went into her =
basement to=20
play.
In the back corner of the =
basement, there=20
was a box full of fun, new toys that Sally had never seen before. =
The one=20
that caught her eye the most though was a plastic, yellow gadget =
with a=20
hook that stretched a spring when pulled.
Immediately, she noticed the =
numbers that=20
ran along the side of her new toy. Being a future "Macon woman," =
it was=20
apparent to Sally Sue that this object has some sort of scientific =
value=20
to it, and she must learn how to use it.
By pulling on the hook, Sally =
Sue soon=20
realized that the spring and numbers could measure the force of a =
pull!=20
How exciting! The more she played, the more her brain began to =
think and=20
discover. Soon enough, Sally Sue took a break to go get a pencil =
and=20
paper. Sally Sue turned her head only to conveniently find a =
useful stool=20
sitting right next to her.
By hooking the her new toy to =
the bottom=20
lip of the stool, Sally Sue pulled with a horizontal force and =
observed=20
the spring as it stretched to reveal the force in which she was =
pulling.=20
Then Sally Sue noticed something new! After the stool moved from =
its=20
restful position, it took less force to keep it going! An amazing=20
discovery!
Sally Sue then took her pen =
and paper and=20
recorded her five trials of observation. With the same type of =
horizontal=20
force, Sally Sue measured the amount of force it took to =
move the=20
stool, then to keep it moving. She then determined that it took an =
average=20
of 11.6 N to move the the stool, and 8.4 N to keep it moving =
across the=20
tile basement floor.
After deciding to weigh the =
stool out of=20
sheer curiosity, it was also recorded that the mass of the stool =
was 4.11=20
kg. Sally Sue, being the brilliant prodigy that she was, worked =
and worked=20
with pencil in hand. Soon after, she discovered equations in which =
to find=20
a friction coefficient for both static and kinetic friction! Once =
again,=20
it was proved that the coefficient of static friction (mu =3D =
0.29) was=20
greater than the coefficient of kinetic friction (mu =3D =
0.21).
The next day Sally Sue =
proudly went to=20
school to announce her new findings. It turns out that Sally Sue =
didn't=20
make a new discovery at all; Newton did. Sally Sue did not end up =
winning=20
the Nobel Prize for this discovery, and only gained the reputation =
of=20
being a huge nerd. Luckily, Sally Sue embraced the nerdiness and =
went on=20
to win the Nobel Prize for making peace with the aliens that =
would=20
invade earth thirty years later.
