Cards (31)

  • 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
