Static Electricity

What does the balloon stick to the wall? (Pick more than one)

• The balloon has a negative charge.

• The wall has a positive charge.

• The wall becomes polarized.

• The balloon has a positive charge.

Which of the following are good INSULATORS? (Check all that apply)

• Glass

• Rubber

• People

• Metal

the negatively charged particle in an atom, moves freely, can be released, shared, or “stolen” from an atom

• proton

• neutron

• electron

Which one is not an insulator?

• plastic

• steel

• rubber

• glass

This is when electrons are rubbed off one object and rubbed onto another

• Friction

• Conduction

• Induction

The negatively charged rod will charge the balloon through induction. Which half of the balloon will become positively charged?

• right half

• left half

• the entire balloon will be positive

• the entire balloon will be negative

These allow electrons to pass through them easily

• Conductors

• Insulators

• Atoms

• Nucleus

Two positively-charged objects would

• repel each other
• attract each other
• not impact each other at all

Charging by friction is

• transfer of protons through rubbing

• transfer of electrons through rubbing

• transfer of electrons by direct contact

• transfer of protons by direct contact

Walking across a carpet is an example of charge being transferred by

• friction.
• induction.
• contact.
• static electricity
