Blogpost Quarter 3 #2

This week in physics we mainly reviewed the lesson that we were learning.  I don't think that I really prepared well for upcoming test that is on tuesday.  I think that the equations will be the easy part of the test while the unit concepts are going to be challenging for me.  On the PA I had a hard time on problems 9 and 10.  I was wondering how do you find h, m, q, and g while it doesn't give you any numbers to start off with.  Although I feel that the free body diagram is pretty easy to draw the challenging part is knowing where there is an electrical force.

Quarter 3 #1

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.
