Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge - positive and negative charge.

The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel each other. Pieces of matter with the same kind of charge attract each other. 2 objects with a positive charge repel each other, as do 2 objects with a negative charge.

Most objects are made of matter with equal amounts of positive and negative charge. Objects with the same # of

How can you disturb the balance of charge on objects so they exert electric force? The easiest way is the same way the ancient Greeks did it - by rubbing the 2 objects together. Rubbing neutral objects together allows charged pieces of matter to move from one object to another.

Neutral objects, like the balloon and the wool, become positively or negatively charged when their charges are disturbed. When an object becomes charged, no new charge is created; charge is simply moved around. This observation has been tested many times and is always true. It is stated a scientific law. The law of conservation of charge states all electric events occur by rearranging or moving charge. The law of conservation of charge holds true for all events, whether in objects as small as atoms or as large as stars.
