Lesson details
Key learning points
- Some objects can be charged by rubbing with certain materials.
- Objects with a static electric charge can exert a force on other objects (that contain electric charge).
- The electrostatic force acts at a distance.
- Objects with opposite electric charges attract each other.
- Objects with the same electric charge as each other repel each other.
Keywords
Static electricity - Static electricity is caused by the build-up of charge on insulators.
Positive charge - A positive charge is a type of electrical charge that is attracted to a negative charge.
Negative charge - A negative charge is a type of electrical charge that is attracted to a positive charge.
Electrostatic force - The electrostatic force is a force that acts between charges.
Common misconception
Pupils often think that ‘negative’ refers to a neutral material, that there is only one type of charge, and that friction creates charge.
Pupils need a secure understanding of the particle model of matter before being introduced to atomic structure. Using dynamic models to help pupils visualise what happens to negative charge can support their progression in understanding.
