What do you know about static
electricity?
Facts to Know
• electrical charge – basic property of the tiny
particles that make up matter; this charge can be
positive or negative
• 0pposite charges – attract
• same charges – repel (push away from each
other)
• static electricity – the build up of charges in one
place; the imbalance of charges
• Negative charges move, but positive charges do
not.
Examples of static charges
Static Electricity
• What would happen if you combed your hair,
then moved the charged comb close to your
hair?
• If you take clothes out of the dryer when they
are slightly damp, they don’t stick together.
Why not?
Answers:
• The opposite charges would cause the comb
to attract the hair.
• Charges can’t be rubbed off unless the clothes
are completely dry.
