(d) Electric charge

Identify common materials that are electrical conductors or insulators, including metals and plastics

Practical: investigate how insulating materials can be charged by friction

Explain how positive and negative electrostatic charges are produced on materials by the loss and gain of electrons

Know that there are forces of attraction between unlike charges and forces of repulsion between like charges

Explain electrostatic phenomena in terms of the movement of electrons

Explain the potential dangers of electrostatic charges, e.g. when fuelling aircraft and tankers

Explain some uses of electrostatic charges, e.g. in photocopiers and inkjet printers
