Anyway, I'm a sophomore in high school, and I'm required to take physical science, but I don't understand any of it. My teacher doesn't help - she doesn't even understand the questions that I have. I actually wasn't doing so bad (still not great, but not terrible) until we got to the discussion on work. Her entire definition is "force times distance". That's simple enough, and all of my math is correct, but I don't understand what "force times distance" really means. I asked the teacher, and she just said, "That's the way it is". OK, fine. But that doesn't really help me learn it! What exactly is work, and why is it force times distance instead of force times time or force times mass? Please help! I'm so frustrated I want to cry. In fact, I've cried several times in this class.
