Types of Charge

This first video features a series of clips involving forces between two different types of rod, and finally the force between a rod and the cloth that is used to charge it.
The video demonstrates the following principles:
  • Charging by Friction
  • There are two types of charge
  • Like charges attract
  • Opposites repel
  • When two objects are charged by rubbing together they gain equal but opposite charges.
