- Physics 2
- The 9 Types of Energy: Heat, Kinetic, Nuclear, Sound, Light, Chemical, Electrical, Gravitational potential & Elastic potential
- Conservation of Energy- The total energy after a change is the same as the total energy before the change- ENERGY CANNOT BE CREATED OR DESTROYED
- Efficiency- The percentage of useful energy coming from a source
- Power= Current x Voltage, Unit of power is the Watt (W) or kilowatt (kW)
- E= Energy (in joules), P= Power (in watts) & T= Time (in seconds)
- Power= Current x Voltage, Unit of power is the Watt (W) or kilowatt (kW)
- Step-up transformers increase voltage whilst, step-down transformers decrease the voltage
- Fuels can be burned to release light and heat energy
- Renewable means unlimited, not running out
- Non-renewable means limited, will eventually run out
- Fuels can be burned to release light and heat energy
- Renewable means unlimited, not running out
- Non-renewable means limited, will eventually run out
- Non-renewable: Fossil fuels, Nuclear fission fuels
- Renewable: Geothermal, Wind (convection currents), Water (dams, tidal, Wave, Solar & Biomass
- Non-renewable means limited, will eventually run out
- Renewable means unlimited, not running out
- Non-renewable: Fossil fuels, Nuclear fission fuels
- Fuels can be burned to release light and heat energy
- Renewable: Geothermal, Wind (convection currents), Water (dams, tidal, Wave, Solar & Biomass
- Non-renewable means limited, will eventually run out
- Renewable means unlimited, not running out
- Wind & Water Powers: Wind Power, Tidal Power, Wave Power & Hydro-electric Power
