This document introduces the concepts of atomic structure, electrostatics, and the three laws of electric charges. It explains that atoms are made up of protons, neutrons, and electrons. Charged objects gain or lose electrons, giving them an excess or deficit. Positively charged objects have fewer electrons, negatively charged objects have more. The three laws are that like charges repel, opposite charges attract, and neutral objects are attracted to charged ones.
10. Introduction to Electrostatics
The Greek
philosopher Thales
(600 B.C.) was the
first to record electric
observations when he
rubbed amber with
fur.
18. 3 Laws of Electric Charges
1) Like charges repel each other.
19. 3 Laws of Electric Charges
2) Opposite charges attract each other.
20. 3 Laws of Electric Charges
3) A charged object will attract a neutral object.
21. 3 Laws of Electric Charges
3 important rules:
i)Objects with like charges repel each other.
ii)Objects with opposite charges attract.
iii)Neutral matter is attracted to charged matter.
