Fill in the Blank

Static electricity occurs when objects obtain a ___ amount of positive or negative charge, creating an imbalance.

Multiple Choice

Which answer best explain why the two pieces of tape repel one another in the image?

• There is a net amount of negative charge on both pieces

• There is a net amount of charge on both pieces

• There are more negative charges on one piece than the other.

Multiple Choice

Which answer best explains why the two pieces of tape attract one another in the image?

• There is a net amount of positive charge between both pieces

• There is a net amount of negative charge between both pieces

• There is a net amount of charge between both pieces

• There is an imbalance of positive and negative charges between both pieces.

Multiple Choice

Which option best describes how electric charges interact?

• Opposite charges attract, while same charges repel one another

• Opposite charge repel, while same charges attract one another

• Positive charges attract both negative and positive charges

• Negative charges attract both negative and positive charges.

Multiple Choice

The charge of a proton is

• Positive

• Negative

• Neutral

Multiple Choice

The charge of an electron is

• Positive

• Negative

• Neutral

Multiple Choice

Which option best describes free electrons?

• Free electrons are easily transferred between the atoms and molecules in materials

• Free electrons are difficult to transfer between the atoms and molecules in materials

• Free electrons do not have a corresponding (partner) proton and are free to move around.

• Free electrons are the amount of excess electrons in a material

Multiple Choice

A rod becomes positively charged after being rubbed with a cloth because it...

• ...is missing electrons, which have been transferred to the cloth

• ...gained protons from the cloth.

• ...gained electrons from the cloth

According to the Law of Conservation of Charge: you can never ___ a net electric charge. Instead charge can only move from one place to another.
