7. Static charge

Available for over a year

In this episode, Ellie and James explore static charge, discuss how it's created, and share some of the key facts you need to know about attraction and repulsion. Suitable for: AQA, Edexcel, OCR. For more information on static charge, check out the BBC Bitesize website: https://www.bbc.co.uk/bitesize/guides/z9s4qhv/revision/1 Key learning objectives discussed in this episode: - 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. The material that gains electrons becomes negatively charged. The material that loses electrons is left with an equal positive charge. - When two electrically charged objects are brought close together, they exert a force on each other. Two objects that carry the same type of charge repel. Two objects that carry different types of charge attract. Attraction and repulsion between two charged objects are examples of non-contact force. Students should be able to: - describe the production of static electricity, and sparking, by rubbing surfaces. - describe evidence that charged objects exert forces of attraction or repulsion on one another when not in contact. - explain how the transfer of electrons between objects can explain the phenomena of static electricity.
