Electricity and Waves Vocabulary

What is the meaning of the term Electric Charge?

• A physical property of matter (positive or negative) that causes it to experience a force.
• A buildup of electric charge on the surface of an object, usually caused by friction.
• A complete, closed path through which electricity can flow.
• The region around a charged object where its force can be felt by others.

Which of the following best defines Static Electricity?

• Materials that allow electricity to flow through them easily.
• A buildup of electric charge on the surface of an object, usually caused by friction.
• A reusable safety switch that automatically flips "off" if the current is too high.
• The stored energy a charge has because of its position in an electric field.

What are Conductors in the context of electricity?

• Materials that block or slow down the flow of electricity.
• A simple tool used to detect the presence of an electric charge.
• Materials that allow electricity to flow through them easily.
• The actual flow of electric charge through a conductor (measured in Amps).

In electrical terms, what is an Insulator?

• Materials that block or slow down the flow of electricity.
• A single unit that converts chemical energy into electrical energy.
• The "friction" that slows down the flow of current.
• A safety device with a thin metal strip that melts if the current gets too high.

What is the primary function of an Electroscope?

• To measure the voltage difference between two points in a circuit.
• To provide energy for a remote control using a standard AA cell.
• To detect the presence of an electric charge using a simple tool.
• To slow down the flow of current like friction.

How is Electric Potential Energy defined?

• The "push" or "pull" between any two charged objects.
• The stored energy a charge has because of its position in an electric field.
• A wave that consists of vibrating electric and magnetic fields.
• The region around a charged object where its force can be felt.

What is a Cell in an electrical circuit?

• A single unit that converts chemical energy into electrical energy.
• A complete, closed path through which electricity can flow.
• The actual flow of electric charge measured in Amps.
• A reusable safety switch that flips off when current is too high.

What does the term Electric Force describe?

• The region around a charged object where force is felt.
• The difference in energy between two points in a circuit.
• The "push" or "pull" between any two charged objects.
• The amount of water flowing through a garden hose.

What is an Electric Field?

• A safety device that melts to break a circuit.
• The region around a charged object where its force can be felt by others.
• The "friction" that slows down the flow of current.
• A wave that requires a medium to travel.

Potential Difference is also known as which of the following terms?
