And I can't sleep.
Have you ever randomly thought of a word, usually it having nothing at all to do with what you're doing or thinking about, and realized you actually have no idea what it means? Maybe it just sounds cool and you really want to use it one day, but to do that, you have to know what it means. I do this a lot, but I had a really bad case of it about thirty minutes ago.
I was about to wash my face and get ready for bed (but not sleep, obviously) and out of nowhere the words angular momentum pop into my head. Where the hell did that come from? I have no idea. I've never even taken physics. But it's a really cool phrase and, if used correctly, could make me sound totally smart. I had to know what it meant. "Ok, just break it down and you can figure it out. No big deal," I thought to myself. My internal argument continued like this:
Angular: obviously, it deals with angles. Easy peasy.
Momentum: a little more difficult to define..it's not really speed it's..it has to do with consistancy, right? Yeah that sounds right..
So..the constant movement of..an angle? A constant angle? Maybe I'm forgetting something..triangles?
Screw it. This is what google.com was made for.
So I looked it up. Surprisingly, I was close. Kinda. I shoulda guessed circles instead of triangles. Angular momentum measures an object's tendency to continue to spin.
Don't ask for an example because I have no idea. But next time I see some one spinning a basketball, believe me when I say that I'll go up and tell them all about angular momentum and they better damn well listen.
If you actually read through all this, kudos to you. :]
