1. Definition of physics the science of matter and energy and their interactions

2. Types of Energy; Heat Light Sound Electrical Chemical Nuclear

3. Definition of electronics the branch of physics that deals with the emission and effects of electrons and with the use of electronic devices VTS_01_3.wmv

4. 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.

5. electrons nucleus protons neutrons Conductor

6. conductors + insulators list some examples of each

9. conductors + insulators How does metallic conduction work

10. 1.5V Cell Cells are cylinders which contain complex mixtures of chemicals. The chemical reactions inside effectively separate + and - charges and produce an electrical current

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