Magickal Force Of Friction! (as told via pictures and words!)
A new force has been discovered by SCIENCE! It is exciting
indeed. It has been dubbed FRICTION by prestigious scientists around the globe.
It is the stuff that keeps things from sliding all over the place. Amazing
Indeed!

Friction is the what makes it possible
for this horseless carriage to move in a forwardish direction!
An astoundingly bright young
scientist named Kate Allen took it upon herself to investigate.
This is the classy
and stylish young lady
Using the most sophisticated scientific methods, the brilliant and
beautiful Kate looked into this "friction" business. Michael with the impossible
to spell last name helped too, but Kate was far more important in the research
of this bewildering phenomenon.
First she gathered her tools:
A
notebook (it was a notebook of SCIENCE!)
some string (also of
SCIENCE!)
a pulley (for the sake of argument, we shall declare said
pulley to be frictionless)
Some conveniently pre-wieghed heavy things (of
SCIENCE!)
She weighed the
notebook of SCIENCE! because it was not conveniently pre-weighed and determined
its mass to be Three Hundred and Seventy-four grams of pure scientific
value.
Then she tied the string of
SCIENCE! to the notebook of SCIENCE! then draped the string over the pulley,
creating an amazingly complex friction measuring device. She discovered that by
using the heavy things, she could determine how much force was required to make
the notebook of SCIENCE! slide across the table in her highly sophisticated
laboratory. She then deduced through intensely complicated scientific reasoning
that the mass required to cause the notebook of SCIENCE! to move from a
standstill would be the force required to overcome STATIC FRICTION! When asked
what Static Friction is, she gave the vague, but impressive sounding, statement
"It's the kind of friction an object experiences when it's just sitting
around."
After this revelation,
she experienced the thrill of discovery again when she came to the conclusion
that if she were to overcome Static Friction by giving the notebook of SCIENCE!
a nudge (a widely recognized and highly accurate unit of force, obviously) and
then measuring how much force was required to keep the notebook of SCIENCE
moving she could determine what force was needed to overcome KINETIC FRICTION.
"It's like static friction, only different and more move-y" says Kate Allen.
Thus, by harnessing the incredible force of gravity Kate Allen was able to
measure FRICTION with great ease.
She was soon left with some really
impressive numbers.
For the notebook of SCIENCE! alone 105g was needed to
make it move and 74g was needed to keep it moving.
Thus, using some more
science we know that these numbers become .105 kg and .074 kg. This was
determined to be the weight of unadulterated scientific
discovery.
Anyway, using further science and a nifty formula ( F(in
Newtons) =mass (in kg) * 9.8 M/s^2 (acceleration due to gravity)) Kate Allen
soon discovered that the forces used were 1.03N and .725N
She then used
yet another formula conveniently discovered by some other less important
scientist. It went something like f=u*N which translates into frictional force=
the coefficient multiplied by the Normal force on an object. Normal force can be
translated into how much an object weighs in Newtons. For the notebook of
SCIENCE! this number is 3.66N
Watch out readers, math is
afoot.
1.03N=u*3.66
ustatic=.281
.725N=u*3.66N
ukinetic=.198
This
science laden process was repeated for the notebook of SCIENCE! with a Five
Hundred gram weight on it
m in
N=8.56N
2.25N=u*8.56N
ustatic=.263
1.67N=u*8.56N
ukinetic=.195N
The
process was repeated once again with just the weight this time. Results were
found.
m in
N=4.90N
.833N=u*4.90N
ustatic=.170
.784N=u*4.90N
ukinetic=.160
In conclusion, Kate Allen is a master of physics and can bend the forces of
nature to suit her will, but more importantly static friction is always greater
than kinetic, numbers are fun to play with, weight has a lot to do with
friction, but sometimes things like surface area and surface texture are
important too. For reelz.
We most work to keep this technology out of the hands of the USSR.
