P3.1 Static and Charge

• What is the definition of static electricity?

  Buildup of electric charges
• Objects with the same electrical charge repel each other.

  True
• What do like electrical charges do to each other?

  Repel
• What is the process called that causes electron transfer in static electricity?

  Friction
• Like electrical charges repel each other.


  True
• The material that loses electrons becomes positively charged
• What is an example of charging by friction?

  Rubbing a balloon on hair
• In charging by conduction, both objects end up with the same charge.


  True
• Charging by induction causes the separation of charges within the neutral object.
• Objects with opposite electrical charges attract each other.

  True
• Static electricity is the buildup of electric charges on the surface of a material, resulting in an imbalance between positive and negative charges
• What is the process called when objects become charged by rubbing them together?

  Charging by friction
• Charging by conduction results in two objects with the same charge

  True
• What is the sudden flow of electric charge from a charged object to another object called?

  Electrical discharge
• When handling charged objects, it is important to avoid creating sparks because they can lead to fires or explosions in flammable environments
• Static discharge can ignite flammable materials

  True
• Static electricity results in an imbalance between positive and negative charges
• Positive and negative charges attract
• Opposite electrical charges attract each other.


  True
• Static electricity occurs when electrons are transferred through friction
• How does charging by friction create an imbalance of charges?

  Electron transfer
• There are three methods of charging objects: friction, conduction, and induction.


  True
• Charging by conduction occurs when a charged object touches a neutral object.
• What is an example of charging by induction?

  Holding a charged balloon near a metal can
• What happens to objects with the same electrical charge?

  They repel
• Positive and positive charges repel each other.
• Objects with the same electric charge repel each other


  True
• The material that loses electrons becomes positively charged, while the material that gains electrons becomes negatively charged
• In charging by induction, the side of the neutral object closer to the charged object acquires the opposite charge, while the other side acquires the same charge
• Lightning is an example of electrical discharge

  True
• What type of clothing is less prone to static buildup?

  Natural fibers like cotton
