Electrostatic Forces 2

Electrostatic Forces 2

1. When two electrically charged objects are brought together they exert a force on each toerh. There are three rules about the forces between charged objects

   • Objects that have the same charge are repelled by each other
   • Objects with different charges are attracted to each other
   • Objects with no carge at all are attracted to charged objects

2. Insulators and Conductors

   • Materials can only be charged this way if they are INSULATORS! This means once the electrons have been transferred, they cannot move through the material back to where they started. Electrons can move easily through ocnductors, such as metals, so it is difficult to charge them by rubbing
