- Energy
- Efficiency
- Sankey diagrams
- Useful energy output / total energy input
- Heat tranfer
- Convection
- Water heating system
- Hot air rises, cold air falls
- Conduction
- Transfer of energy when particles pass vibrations on
- Radiation
- Absorbed by matt black, which also emits radiation
- Convection
- Work, KE and GPE
- GPE = mass x gravity x hieght
- Energy transferred = force x distance
- KE = 1/2 x mass x speed^2
- Power
- Work done / time taken
- 1 watt = 1 joule of energy transferred per second
- Thermos flasks and insulation
- double glazing, carpets, cavity wall insulation...
- Flasks: vacuum, silvered surface, cap
- Power stations
- wind turbines
- water power
- Geo-thermal
- solar heating
- solar cells
- fossil fuels
- Nuclear
- Energy types
- Most Kids Hate Learning GCSE Energy Names
- Magnetic, Kinetic, Heat, Light, Gravitational potential, Chemical, Sound, Elastic, Nuclear
