- Static Electricity
- When some insulating materials are rubbed against each other they become electrically charged
- Negatively charged electrons will be rubbed off one and put onto the other
- The material that gains electrons will become negatively charged
- The material that loses the electrons will be left with an equal positive charge
- Electrically charged objects will attract small objects that are placed near them
- Eg. rubbing a balloon on wool and then putting it by your hair
- Positive static charges are caused by electrons moving
- Only the electrons move
- When electrically charged objects are brought together they exert a force on each other
- Two objects with opposite electric charges will attract each other
- Two objects with the same electric charge will repel each other
- The forces felt by the objects get weaker as they're moved further away from each other
- OPPOSITES ATTRACT
- Electrical charges can move easily though conductors
- Eg. metals
- When some insulating materials are rubbed against each other they become electrically charged
