This unit had a lot to do with charges. The picture above depicts this object my roommate has that sticks to the metal part of her desk with a magnet. This means that the metal on the desk and the magnet are different charges. Either positive and negative, positive and neutral, or negative and neutral. All of these combinations would result in the attraction needed for the object to stick to her desk. It's quite interesting to realize that things I see every day have something to do with physics. Also, in the upper left part of the picture, you can see part of my roommate's Justin Bieber poster. They must be different charges, because she is quite attracted to him.
