As juniors in high school our physics teacher introduced us to the concept of energy and its two forms: POTENTIAL and KINETIC. Mr. Hale placed a piece of chalk on a desk and said, "This is potential energy." The chalk just sat there. Then with his finger, he gave the chalk a nudge. "This," he said as it rolled off the desk and was in free-fall, "is kinetic energy." The correlation logged in my brain:
kinetic energy = movement
potential energy = just sits there
potential can / kinetic does
potential revs the engine / kinetic squeals the tires
potential energy = just sits there
potential can / kinetic does
potential revs the engine / kinetic squeals the tires
Potential is... FIXIN TO...
Here's a thought, huge potential gets less done (about zero) than a tiny bit of kinetic.
Energy is the ability to do work; or if you'll allow me - to do something.
A simple version of the Law of the Conservation of Energy states, Energy cannot be created nor destroyed. It can only be stored or transferred. This begs a question: Am I just storing up, or am I transferring?
So why the lesson on forms of energy? Because we can be fixin' to... for only so long.
Big Potential... but it must leave the launching pad! |
I'm fixin' to go.
For now...
