What is the primary difference between static electricity and dynamic electricity?

• Static electricity flows continuously, while dynamic electricity does not.
• Dynamic electricity flows, while static electricity does not.
• Dynamic electricity is only found in nature, while static electricity is man-made.
• Static electricity is used in batteries, while dynamic electricity powers devices.

How is static electricity generated when rubbing a balloon on your hair?

• The balloon absorbs heat from your hair.
• The hair loses moisture to the balloon.
• Electrons move from your hair to the balloon.
• Electrons move from the balloon to your hair.

What happens to static electricity during a thunderstorm?

• It becomes dynamic electricity
• It flows through wires
• It accumulates in clouds
• It disappears completely

What is the role of electrons in dynamic electricity?

• They create static electricity.
• They are only found in insulators.
• They flow through conductors.
• They do not move.

What is an example of static electricity in nature?
