Electricity Year 8

Describe two possible ways (friction or contact) in which objects acquire an electrostatic charge.

How can objects acquire an electrostatic charge through friction?

• 1. By rubbing two neutral objects together
• 2. By touching a charged object
• 3. By exposure to sunlight
• 4. By dropping the object

How can objects acquire an electrostatic charge through contact?

• 1. By rubbing two neutral objects together
• 2. By touching a charged object
• 3. By exposure to sunlight
• 4. By dropping the object

Which type of electrostatic charge results when two objects with different materials are rubbed together?

• 1. Positive and negative
• 2. Negative and negative
• 3. Positive and positive
• 4. None of the above

When a positively charged object and a negatively charged object are brought near each other, what happens?

• 1. They attract each other
• 2. They repel each other
• 3. They remain neutral
• 4. They cancel each other out

What happens when two like charges are brought close together?

• 1. They attract each other
• 2. They repel each other
• 3. They remain neutral
• 4. None of the above

What happens when two unlike charges are brought close together?

• 1. They attract each other
• 2. They repel each other
• 3. They remain neutral
• 4. None of the above

When a charged and an uncharged object are brought close together, what happens?

What are the three subatomic particles that make up an atom?

• 1. Electrons, protons, and neutrons
• 2. Protons, electrons, and photons
• 3. Neutrons, photons, and electrons
• 4. Protons, neutrons, and photons

What is the charge of a proton?

• 1. Positive
