Physics

• Kinetic - Anyrhing that MOVES has kinetic energy
• Chemical - anything with STORED ENERGY which can be released by a chemical reaction
• Light - Anything LUMINOUS gives off light energy
• Heat (Thermal) - Anything with a temperature has heat energy
• electricity in our homes come from the national power grid aka power station
• Magnets- When you put two ends of a magnet together they repel
• Magnets - When you put two different ends together they attract
• Electricity is produced when metal wire is moved in a magnetic field
• Fossil Fuels - Coal, oil, and natural gas
• Nuclear fuels like uranium
• The main stages of generation of electricity at a Power station -

  1. The fuel heats water in the BOILER. This produces steam
  2. The steam turns the TURBINE
  3. Electricity is produced in the GENERATOR
• Power stations in NI

  1. Coolkeeragh OIL 180MW
  2. Ballylumford GAS 950MW
  3. Kilroot COAL/OIL 600MW
• To get to Ballylumford from Scotland to get a gas supply they use a pipeline under the sea
• Oil, coal, natural gas are called fossil fuels because they are made from thing which were once alive
• Coal was formed by dead plants that sank into the swamps and eventually rotten to form the layer of peat. After millions of years the heat and pressure turned it into coal.
• The difference between the way coal and oil was formed is that Oil is from animals and Coal is from the swamps.

  The similarities are they both form for 100 millions of years
