Friction and Generation of Static Electricity


  • Friction between surfaces: When two surfaces rub against each other, electrons are transferred between them due to the contact and separation of the surfaces.

  • Movement of electrons: The movement of electrons between surfaces generates static electricity.

  • Definition of static electricity: Static electricity is the build-up of electric charge on the surface of objects due to the movement of electrons.

  • Causes of static electricity: Friction, contact, and separation of materials can all contribute to the generation of static electricity.

  • Use of static electricity: Static electricity can be used in various applications such as electrostatic painting, air purifiers, and photocopiers.
