Friction is

 

 

 

 

 

The force that keeps happy mountains…

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

…from falling apart

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

And a happy person…

 

 

 

 

 

 

 

 

 

 

 

 

 

 

…from doing the same.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

And so laughingly with chortling chuckles we ne’er-crossly transverse the world as Scottish bairns infantile in our comprehension of the mythic etiology or teleology of that staid unmoving mistress Friction, goddess of immobility budging solely for those juggernauts US who pursue with common complicity the explication of said madam efficaciously hereon with more point to the fact in point of fact simplicity.

 

Simplicity: Let’s get up to business!

 

Friction can be described mathematically, verbally, nonsensically, with circumlocution, or not at all depending on the YOUser’s preference.

 

I regardless of the unidentified user and regardful of me will start withal with a verbal explanation—and one short, quick, and terse—as the alphabet I choose for my medium.  Read this:

 

 

 

 

 

 

So simplicitous!  Now, to rest your text-wearied eyes I extend graciously to those who explored my analytical definition of friction a picture (for those contumacious, recusant scamps insistent upon disobedience I enjoin imperatively and aloud “Fie! Look up and read the verdurously-scintillating letters, barring none, and surmount doughtily the not-taxing task!”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Now, 4 those more 2ned 2 math I give you it numberless:

 

 

To verbalize (my specialty):  The force of friction equals the normal force times the coefficient of friction.  The coefficient of friction is the scalar value describing the ratio of friction between two surfaces, and it is always between 0 and 1—the higher the number the greater the friction.

 

 

 

But you don’t not know nothing yet.

 

There are two kinds of Friction.

 

Static Friction (μ_s)

• Static friction is the force between two relatively unmoving objects.  Its what keeps them unmoving!  Here’s an illustrationà   HOWDYHOWDYHOWDYHOWDY
• The HOWDYs aren’t moving with respect to each other—no matter how fast you scroll.  That’s static friction.

 

 

Kinetic Friction (μ_k)

• Kinetic friction is the force between two objects in motion relative to each other.  It acts in the direction opposite the motion. 
• Two principal kinds of kinetic friction exist. 
• The first is sliding friction, between two touching solidsà 
• The second is fluid friction, between a solid and the fluid through which

      it movesà

Now we have the words and the math down.  Ahhhh, there it is, the riddle unraveled, friction in its pure and simple splendor.

 

 

 

Naturally, as all things that are are, you might ask

 

 

 

$%^%^(( (*& SO WHAT?!?!?!$%^&()!@#

Heed my imparting of advice: We’ve the gist down, (or, visually, up), and I, genuflecting and thereby muddying my pristine achromatic surplice through supplication, implore you to proceed down to matters more weighty, more prone to grinding a brain caught in a world of FRICTION.
