Coefficient of Friction

Every day–or at least many days–I try to write a blog, but current events dissuade me. I confess, I automatically select Netflix when I turn on the television, even though if my granddaughters have been here, I’m immediately exposed to ICarly. (I never knew that any children’s television program could induce urticaria, borborygmi, and myclonus. Mighty Mouse never did.)

Current events, especially in Washington, DC, are so–so–so, you know. It makes it difficult to write anything that doesn’t sound desperate. I’ve got two dozen blogs I started but I haven’t finished, because of that.

So why today’s title? It should be obvious: Friction force develops between contacting surfaces of two bodies and acts to resist relative motion between the bodies. The friction force, F, is proportional to the normal force, N, and the coefficient of friction, μ.

Still not tracking?

Okay. Whenever I have an idea for a blog and then become exposed to current events, the idea either slips away on its own, or else I push it out of the way. There is not enough friction to keep it in one place.

It’s pathetic, I know, but this is the world in which we live.
