Ye Olde 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.
