Examples of Electrostatics in the world are: A doorknob shock Static in the dryer Your hair standing up when combed
Electricity at rest Involves electrical charges, the forces between them, and their behavior in materials
Mutual attractions or repulsions between electrons or protons is called charge. Charges can be negative (-) or positive (+)
Protons= positively charged Neutrons= no charge, not repelled or attracted to other particles Electrons= negatively charged
Draw a picture to represent the saying above.
Law of conservation : the principle that electric charge can neither be created nor destroyed. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved.electric chargepositive chargenegative charge conserved The first written statement of the principle was by American scientist and statesman Benjamin Franklin in 1747.Benjamin Franklin
Material in which an electrical charge can flow Examples: copper, metal, your body, water
