Static electricity

    Cards (13)

    • Electrostatic forces are the forces between charges
    • Like charges repel eachother; AKA electrostatic repulsion
    • Opposite charges attract eachother; AKA electrostatic attraction
    • Electrons can be moved from one object to another using friction
    • For an object to have a negative charge, it would take another object's electrons
    • For an object to have a positive charge, it would give another object electrons
    • Materials like human skin, leather, wool, fur, silk, and aluminium are more likely to lose electrons
    • Materials like wood, amber, hard rubber, polyester, plastics, and silicon are more likely to attract electrons
    • A neutral object can be attracted to a charged object
    • Electrons move around however protons and neutrons are tightly secured in the nucleus of an atom
    • Static electricity is the imbalance of charges within or on the surface of a material
    • The Van De Graaff Generator uses static electricity on a moving belt to positively charge a large metal sphere as it carries the electrons away.
    • An insulator is a substance that does not allow free movement of electrons through its structure
