Electricity

What is electric force? 

• The region around a charged object where the object’s electric force interacts with other charged objects
• The attraction or repulsion between electrical charges
• A continuous flow of electric charges through a material

What is it called when the force that one surface exerts on another when the two surfaces rub against each other?

• Friction
• Static electricity 

What is a electrical current?

• A continuous flow of electric charges through a material
• A complete, unbroken path through which electric charges can flow

What are some examples of conductors?

• Rubber, glass, sand, plastic, wood
• Metals such as silver, copper, aluminum, and iron are good conductors

What is a Insulator?

• A material that does NOT conduct heat well, a material through which charges cannot easily flow
• A material that does conduct heat well; a material through which charges can easily flow

What is voltage?

• The difference in electrical potential energy between two places in a circuit
• the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere

What is a electrical field?

• A continuous flow of electric charges through a material
• The region around a charged object where the object’s electric force interacts with other charged objects

What is a buildup of charges on an object?

• Static Electricity
• Friction

What is a conservation of Charge?

• A continuous flow of electric charges through a material
• The law that states that charges are neither created nor destroyed but only transferred from one material to another

What is a complete, unbroken path through which electric charges can flow?

• Electric Circuit
• Electric Current
