  • Definition of physicsthe science of matter and energy and their interactions

  • Types of Energy;

    Heat

    Light

    Sound

    Electrical

    Chemical

    Nuclear

  • Definition of electronicsthe branch of physics that deals with the emission and effects of electrons and with the use of electronic devices

  • There are two types of electricity;

    Static Electricity. ( this is a build up of electrical charge on insulators)

    Current electricity. Easily the most important and useful form. This type flows along conductors. Moving currents can produce heat, light + magnetic fields.

  • conductors + insulatorslist some examples of each

  • conductors + insulatorsHow does metallic conduction work

  • 1.5V CellCells are cylinders which contain complex mixtures of chemicals. The chemical reactions inside effectively separate + and - charges and produce an electrical current

  • A battery is a group of cells. Here two 1.5V cells are in series and produce 3V
