Revision Motion Test Define work as the transfer of energy through the application of force including hooke's law Spring/elastic band challenge Power of a physics student PLC Physics 2004 Unit 2 - Electricity Context: Time: Lesson DC devices,household and car electricity 15 lessons. TOPIC Comments 1 Revise electrostatics Define current,Voltage and Resitance Can use Hewitt's video. Just the basics. V,I and R should be carried over from Yr 10 2 Simple circuits Predicting bulb brightness Building circuits Use simple parallel and series circuits to get the basics established. This should also include POE with hands on circuit building. Most of this should be revision from yr 10 3 Using meters Units of V and I 4 5 Measuring I and V in series and parallel Resistance How does it relate to V and I? Really I relates to V and R! Resistance What does it depend on? 6 Resistance in plarallel and series circuits Relevant equations. Lots of practice questions 7 Modeling electric circuits Use crocodile clips to model simple circuits. 8 Ohm's law 9 Ohmic and Non Ohmic devices 10 Houshold and car electricity 11 Effects of electrical shock 12 13 Electric Power Paying for electricity 14 Revision 15 Test Practical: actual and/or model Start with the V/I charateristic of a lightbulb. Discuss v/I 's of diodes, LDR's etc Including Earth, fuses, circuit breakers. Causes effects and treatments P = VI (Important for DS 3.3) Introduce kWh Home work WORK DUE PLC Physics 2004 VCE Physics: Unit 2 Context: Time frame: Lesson 1 2 Investigation: Alternative Energy Sources Photo voltaic Electricity 15 lessons.
