In this lab we used vinyl and acetate, we observed how they reacted when being charged with static electricity. Vinyl carries a negative charged when being rubbed with wool, and acetate carries a positive charge when being rubbed with cotton. When two positively charged objects are close together causes a repel away from each other. When two negatives are close together they stay neutral and don’t move. When their is a negative and a positive they attract.
When a neutral object is close to a charged object it causes an attraction. The charged balloon attracted the neutral meter stick.
