End of Easter break + physics + tests
So. What happened to the end of Easter break?
Thursday through Saturday. Not studying, but reading books and pulling network cables. Well; after I wrote about the first half, things started to deteriorate, of course. That was ok-I had expected it to. I had been putting off studying physics, and was worrying about that during Thursday and Friday, although I studied very little. On Friday night I started rereading "Poison Study" by Maria Snyder (that is a great book, really). On Saturday, I first read some, although I shouldn't, and then Lina and I had to pull network cables through the house, which took all afternoon and left me tired and cranky and in no mood to study.
Studying. Oh, whence is this force? I did anyway, and studied, and struggled with the dumb collisions. Yes, energy has to be conserved, and so, the kinetic energy which carries two objects into one another will have to carry them away, too, because it cannot disappear once they have collided. But what is actually happening? Throwing a ball at a wall, why does the normal force of the wall not only stop the ball (which is what the normal force is supposed to do, it is merely a reaction force) but push the ball away again? Where does that force come from, to push it away? I do not know. And Dad couldn't tell me, either, and it's frustrating. He claims not to think of things from a force perspective, only from an energy perspective. I don't know what energy is, not really. It's supposed to be a particle or a wave, but it seems it never actually is. I at least have some vague idea of what force is. Or maybe I don't. But I know how it works. It's something that one body (or field) exerts on another body. The wall exerts that extra force on the ball, to make it bounce away. But the normal force shouldn't do such a thing. So what force is it, then? And where does it come from? Sigh.
Reading late. So I went to bed rather late, being rather upset, on Saturday night. In fact, I think after Brian had gone, I spent like three hours, I think, finishing up Poison Study. It was already getting light by the time I went to sleep.
Sunday. Pulling more cables, and studying. When I woke, it was already afternoon, and I had to finish pulling those cables. It wasn't actually as upsetting as it had been on Saturday, although I was worried, because when would I study? but I studied after I was done, in the evening, and until rather late. This time it was circular motion and gravitation, which were both easier to understand than my mystery rebound force. I was pretty much done with the studying I needed to do, leaving Monday to practice problems. So while I was tired, I was content when I went.
Monday. Back to school. No test! What?! But when I get back to school on Monday, the first thing I hear is, Behzad postponed the test! He's including another chapter (rotational motion, which is different from circular motion by quite a bit), and we now have two weeks to learn that chapter too. Joy. =P I was at first disappointed, now that I'd worried so during the latter half of the break, but then relieved, because ... I was so tired on Monday after school that I fell asleep at 7 o'clock, and I didn't wake until 11. I stayed up a bit too late talking to Brian, but ehhh.
Tests back! And from my excitement, you can tell, they went well, better than I had hoped. =P I also! Got two tests back! I got my final Math C test back (the one I did when I was sick and that I screwed over) and I did surprisingly well on it, getting all the MVG-points on it. I also got my biology test back, and I had an MVG on that too! I was really happy about that, because I only had VG+ in that class previously, because the MVG questions are always weird in that class, and I have to include all the right things, but it's hard for me to know. This time I did well though, and unless I screw up the last two things in that course, I'll get MVG in it. *nods proudly*
And that's the end to altogether too much rambling. Sheesh Anna. Not like anyone really cares, anyway; or ever reads it, either. =P
And oh, I guess it's the first of April today, huh. Well, what do you know. =P
