TRANSCRIPT

  • * of 5 Boardworks Ltd 2011

    This excerpt is five slides from the Static Electricity presentation in GCSE Additional Physics.

  • How does static charge build up?

    * of 5 Boardworks Ltd 2011Static charge can build up when two insulating materials are rubbed together, such as a plastic comb moving through hair.Friction between the materials causes electrons to be transferred from one material to the other:one material ends up with more electrons, so it now has an overall negative charge

    one material ends up with fewer electrons, so it now has an overall positive charge.

  • Where does static charge come from?

    * of 5 Boardworks Ltd 2011All materials are made of atoms, which contain electric charges.An atom has equal numbers of electrons and protons and so has no overall charge.Electrons do not always stay attached to atoms and can sometimes be removed by rubbing.

    The PowerPoint format means that you can reveal information step-by-step at the pace that suits your class.

  • Charging materials

    This animated activity introducing the topic of charging materials could be used as a precursor to work in the lab.

    Exciting virtual experiments demonstrate the science behind observed phenomena.
