Static electricity

a) When certain insulating materials are rubbed against each other they become electrically charged. Negatively charged electrons are rubbed off one material and onto the other.

See Static Electricity

 

 

b) The material that gains electrons becomes negatively charged. The material that loses electrons is left with an equal positive charge.

See Charge
c) When two electrically charged objects are brought together they exert a force on each other.

d) Two objects that carry the same type of charge repel. Two objects that carry different types of charge attract.

e) Electrical charges can move easily through some substances, eg metals.
