When one part of a balloon is rubbed with wool, the wool gives up electrons to the balloon. The balloon will cling to other objects because it has a _________.
negative charge
400
Ordinarily every object carries equal numbers of protons and electrons and is said to have a __________.
neutral charge
500
The sudden movement of a charge. Zap!
discharge

The buildup of negative particles at the bottom of the thundercloud is so great that a discharge jumps to the ground. This creates lightning which releases 4 kinds of energy. What are the 4 kinds of energy released.
sound, heat, light, electrical
500
Objects with no charge have an equal number of ________.
protons and electrons

When you take off your wool hat, it rubs against your hair. Electrons move from your hair to the hat. Now each of the hairs has the same positive charge. So the hairs try to get as far from each other as possible. The farthest they can get is by standing up and away from the others. Why are you having a bad hair day?
Each hair is positively charged, and things with the same charge repel each other.
