Why matter is said to be electrical in nature

A comb can be charged by friction. Rubbing it with wool will cause it to gain electrons from the wool, so the comb will have a negative charge. If you bring the now negatively charged comb near a neutral pith ball, the electrons in the pith ball will realign themselves and move away from the side of the pith ball nearest the comb.

The pith ball is still neutral overall because no electrons have been gained or lost. However, the side of the pith ball nearest the charged comb will be attracted to the comb as if it had an opposite charge, which it only has on that one side because the electrons have moved away from the like charge on the comb. This is charge by induction.

Negatively charged comb attracts neutral pith ball but they do not touch. If the pith ball and comb touch, electrons actually move from the comb to the pith ball. The side of the pith ball that has touched the comb now has the same charge as the object that touched it. The pith ball repels from the comb.

This is charge by contact. Neutral pith ball becomes negative when it contacts comb Contact Negative pith ball and negative comb repel each other. Like charges repel. In your notebooks, write down three things you learned in class today. On your copy of these notes, highlight the most important words. Then, write three questions you would like us to answer in this unit.
