1. Static electricity The atomRules for charges + and + -and – -+ and - Relative charge Releative mass Proton Neutron Electron Electrostatic paint spraying - ExplainDangers - explain How do objects become charged

2. Electricity Voltage / current graphs A wire obeying ohms law is here. Draw in a diode and a filament lamp Equations Units Power = Voltage = Current = Resistance = Energy transferred = Charge = Series and parallel circuits Diagrams of each and what happens in each How do we measure resistance Label all parts V A ComponentSymbol Diode Bulb Resistor Variable resistor Voltmeter LDR Thermistor Cell Ammeter

3. Vectors and velocity Graphs Equations (can you also rearrange) Acceleration = Velocity = Force = Weight = Momentum = Work done (energy transferred) = Kinetic energy = Gravitational potential energy = Units Speed / velocity Distance Time Force Acceleration Mass Weight Gravity Momentum Car safety features Relate momentum and time to keeping safe in a crash Draw diagrams to show how you calculate the resultant force Terminal velocity What happens when a force is balanced What happens when a force is unbalanced Stopping distance = thinking distance + braking distance (what effect each)

4. Radiation Protons Neutrons Electrons U 235 92 Isotopes FissionFusion Type of radiation SymbolMade ofIonising ability Stopped by uses Alpha Beta Gamma Uses of radiation (explain how they work) Smoke detector uses – Testing paper thickness – Detecting leaks in pipes uses – Half life – What is the half life on this graph
