So this past week I didn't learn too much about charges... we had a sub and most people sat around playing Tetris Battle. :) But we did talk about electric fields and forces... kind of. We talked about electric fields... the more charge you have, the bigger the electric field. Which is kind of like the more children you have, the bigger your home should be to accomodate them. Anyhoo, the arrows in this electric field are pointing away from the charge, meaning that the field's charge is positive. On the other hand, if arrows were pointing TOWARD the charge, the charge of the field would be negative. Also, if the number of arrows on this picture were doubled, guess what? Yeah, that's right, geniuses. The charge would be doubled, too. Another thing I learned (TODAY, haha) was about electroscopes. They're these stick-figure-without-any-arms things that are electrically neutral and can change charges and move the "legs" of the stick figure when the charges are changed. Also, these electroscopes can be polarized: when charges move to create a positive side and a negative side, effectively dividing them. So, that's all, folks. I don't really have much else to go on about. Shooots :)
