This week in Physics we are learning about positive and negative charges. When doing the lab I realized that when applying friction to something it becomes charged. Weather it becomes a postitive or negative we do not know. I was wondering if there was a way to tell what the tapes were charged while doing the lab. Me and Joe tried to put it to a postitive end of a battery to see if there would an attraction or a repelling effect on the tape. It turned out that it didn't matter weather the positive end or the negative end of the battery, the tape was attracted to both sides. I also learned that when touching the tape it regains a neutral charge because our bodies take away or give that extra electron to bring the charge of the tape back to neutral.
