Static Electricity Video

What causes static electricity?

• A net amount of positive or negative electric charge on an object.

• The continuous flow of electrons through a conductor.

• The attraction between protons and neutrons in an atom.

• The transfer of heat between two objects.

Why do you think the tape repels each other?

What does it take for an atom to be electrically neutral? (Talk about what has to be in balance.)

How do conductors and insulators differ in terms of electron movement?

• Conductors allow free electrons to move freely, while insulators hold onto them tightly.

• Conductors hold onto electrons tightly, while insulators allow them to move freely.

• Conductors only allow positive charges to move, while insulators only allow negative charges.

• Conductors and insulators both allow electrons to move freely, but at different speeds.

How do insulators and conductors differ in terms of electrons? (At least 2 sentences)

When a glass rod is rubbed with a cloth, what happens to the rod's charge?

• It gains a net positive charge.

• It gains a net negative charge.

• It remains electrically neutral.

• It becomes polarized but retains a neutral net charge.

What does the Law of Conservation of Electric Charge state?

• Electric charge can only move from one place to another, it cannot be created or destroyed.

• Electric charge can be created but not destroyed.

• Electric charge can be destroyed but not created.

• The total electric charge in the universe is constantly increasing.

What is the key difference between charging by induction and charging by contact?

• Charging by induction creates a net charge without physical contact, while charging by contact requires objects to touch.

• Charging by induction only works with insulators, while charging by contact only works with conductors.

• Charging by induction results in opposite charges, while charging by contact results in like charges.

• Charging by induction involves the creation of new charges, while charging by contact involves charge transfer.
