Static Electricity

Question	Answer
What causes a build up of static?	Friction
What happens when certain insulating materials are rubbed together?	Negatively charged electrons will be scraped of one and dumped on the other. This leaves a positive static charge on one and a negative charge on the other
Why may a balloon be attracted towards an object with static charge?	Electrically charged objects attract small objects placed near them
Which charge doesn't move as a result of static electricity?	The positive charges
What is a positive static charge caused by?	Electrons moving away elsewhere
What happens to the material that looses some electrons?	It looses some negative charge and is left with an equal positive charge
What happens when two electrically charged objects are brought close together?	They exert a force on one another
How do forces of attraction get weaker?	The further apart they are
What can charges move easily through?	Conductors
Why does some static electricity end up with a spark or shock?	Because there's a build up of charges in one place
What is static electricity about?	The charges which are not free to move
