Kinetic Energy and Potential Energy

Think back to elementary school science class. Remember learning about kinetic energy and potential energy? I was smitten with the word “kinetic” from the moment I heard it–that word is not one you bump into by accident. It is a book-learning, SAT kind of word. I’ve been thinking a lot about kinetic energy and potential energy this morning as I try to get myself packed to go to a writing retreat. I have re-organized our silverware drawer, talked to my insurance agent, folded everything that needs folding, and even done a few chores for other people because I am a bundle of nerves. I am downright kinetic.

So, in case you are having trouble finding that fourth grade science part of your brain, a refresher: imagine an archer, pulling back the string of a bow. Potential energy is “the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.” So when the archer pulls back on the bowstring, the string possesses a great amount of potential energy, all derived from the force the archer’s muscles can pull, the tautness of the string itself, the angle at which the string is stretched, etc. When the archer’s fingers let slip, we are watching kinetic energy as the arrow is pushed forward by the released energy of the bowstring. Kinetic energy is the energy of being in motion.

For potential to move to kinetic, the archer has to LET GO.

Last week, when I wrote about the challenge I’m facing with writing, Margaret reminded me of something our boot camp coach Tami used to say: if you want to run faster, you have to run faster. Simple in words, but hard in dead…right? Margaret pushed through her PhD with those words. Tami moved herself from a nursing career to an interior design career. To achieve the thing you want, you have to DO the thing you dream of. The only way to train your body to run faster is to push it to run faster. Not to talk about running, watching Chariots of Fire every night, join a running list serv, or shop for new shoes. You get better at running by running.

That got me thinking (see how I’ve been doing allllll this thinking but no writing?) about Wise Heather. Heather has been training for MONTHS for the Marine Corps Marathon. It’s her first full marathon and it’s this weekend. She’s running in memory of her father. She has hit every mark of her training plan, mile after mile after mile. She’s run in wind and rain and heat and other cities and other races. She knows the course elevation. She knows the forecasted temperatures. She knows she has to “beat the bridge” at mile 18 and she has practiced running that far, that fast.

Then her training plan told her to quit running. Not quit altogether, but quit pushing herself higher. This is the dreaded “taper” that runners have to do before a race. Cut the mileage back, let your muscles rest, all with the aim of going farther and faster because you slowed down.

Heather is pulling the bowstring and it is HARD. Building up potential energy requires those stresses in oneself. Waiting to let the string go and see how far it can push the arrow, in the right direction, if the wind is right.

I am writing these words, right now, about her, and about math and science and Margaret and Tami and elementary school, because I really want to be writing a book and it is HARD. I think about writing and talk about writing and read books written by people who know how to write. But the only way to write more is to write more. In sun and wind and rain and in other cities.

So. My car is packed. The string is pulled. Now I just have to let go. Change potential into kinetic.

This Saturday, think of Heather and remind her that she can do this. At the same time she is running her race, I will be writing mine. We can do this. Potential to kinetic.

Let’s go.
