Exploring Electric Charges and Static Electricity

What happens when two positively charged protons come together?

• They neutralize each other.

• They form a new element.

• They attract each other.

• They repel each other.

What is an electric field?

• A magnetic field created by electric charges.

• A field where electric currents flow continuously.

• A region where protons and neutrons interact.

• A region around a charged object where the object's electric force is exerted.

What does the term 'static' in static electricity mean?

• Moving continuously

• Not moving

• Changing direction

• Flowing rapidly

Why are metals good conductors of electricity?

• They have free electrons that can move easily.

• They are insulators.

• They have a high number of protons.

• They have tightly bound electrons.

What is charging by friction?

• Transfer of electrons by rubbing two objects together.

• Transfer of electrons by induction.

• Transfer of electrons by direct contact.

• Transfer of electrons through a conductor.

How does charging by conduction occur?

• By using an insulator.

• By induction without direct contact.

• By direct contact between a charged object and another object.

• By rubbing two objects together.

What is an example of charging by induction?

• Rubbing a balloon on your hair and sticking it to a door.

• Using a metal object to transfer charge.

• Walking on a carpet and touching a doorknob.

• Using a plastic spoon to charge an object.

What causes the spark in static discharge?

• Cooling down of the air around transferring electrons.

• Heating up of the air around transferring electrons.

• Movement of protons.

• Movement of neutrons.
