Electrostatics Lesson

Open Ended

How do you think the convention of assigning positive and negative signs to charge influences scientific communication and understanding?

Multiple Choice

Why is the concept of electric charge significant in understanding the behavior of matter?

• Because it determines the color of substances

• Because it holds molecules and atoms together

• Because it affects the temperature of objects

• Because it controls the size of particles

Multiple Choice

Which subatomic particle is responsible for a negative charge?

• Proton

• Neutron

• Electron

• Photon

Open Ended

Explain the difference between static electricity and current electricity.

Multiple Select

Which of the following are types of materials based on their electrical conductivity?

• Insulators

• Conductors

• Semiconductors

• All of the above

Multiple Choice

What happens when two objects with like charges are brought close to each other?

• They attract each other

• They repel each other

• They combine to form a neutral object

• They lose their charge

Open Ended

Describe two ways to charge an insulator and explain how each method works.

Multiple Choice

Which process involves transferring charge by direct contact between a charged object and a neutral object?

• Charging by conduction

• Charging by induction

• Polarization

• Electrostatic attraction

Open Ended

Explain how polarization allows a charged balloon to attract a neutral object like wood.

Multiple Select

Which of the following statements about water molecules and their interaction with charged objects is/are correct?

• Water molecules are polar.

• Water molecules can align themselves to be attracted to charged objects.

• Water molecules are always neutral and cannot be attracted to charged objects.

• Water molecules are deflected by the presence of a charged object.
