1

What is the build up of static electricity caused by?

Friction

2

How does static electricity occur?

1) When certain insulating materials are rubbed together, negatively charged electrons will be scraped off and dumped on the other
2) This'll leave a positive static charge on one and a negative static charge on the other

3

What determines which way the electrons are transferred?

The 2 materials involved

4

Describe the transfer of electrons when rubbing a polythene rod and a cloth duster

Electrons move from the duster to the rod. Duster is then +ve charged and rod is -ve charged

5

Describe the transfer of electrons when rubbing a Acetate rod and a cloth duster

Electrons move from the rod to the duster. Duster is then -ve charged and rod is +ve charged

6

The material that loses the [ ] loses some negative charge and is left with an equal [ ]

electrons
positive charge.

7

Only [ ] move - not the positive charge!

electrons

8

Two things with opposite electric charges...

are attracted to each other

9

Two things with the same electric charges...

will repel each other

10

The forces that make objects attract/repel each other get [ ] he further apart the two things are.

weaker

11

Electrical charges can move easily through [ ]
