Electric Forces

1. Electric Charge

   • Types
     • Like=Repel
       • ++/- -
     • Positive= +q
     • Negative= - q
     • Unlike= Attract
       • + -/- +
   • Properties
     • Kinds of Charges
       • ↗️
       • Conservaion of charges=No charge is created or destroyed
         • Quantized electric charge= Coulomb(C) is the unit for electric charge
           • Types of Materials
             • Conductors: Material in which charges move freely.
               • Like Metals
             • Insulators: Material in which charges do not flow freely
             • Semicondutors: Characteristics in between
             • Superconductors: Zero electrical resistance
             • How objects charges:
               • Conduction:Direct contact
                 • Friction
               • Positives and Negatives charges in the same object
               • Induction: Charging by bringing near another charged object and grounding the conductor
               • Coulomb's Law
                 • The closer 2 charges are the charges, the greater the force between them
                 • Forces are equal when charged objects are in equilibrium
