Transcript

  • 1. A battery storeschemical energy.Chemical energyFood is stored chemical energy.This is storedenergy containedin chemical compounds.Chemical energy is released duringchemical reactions.
  • 2. Electrical energyElectric charge travelsthrough wires in a circuit.This is energyproduced by the flowof electric charge.
  • 3. HEATThermal energyenergy transfermovement ofatoms andmoleculesThis is energy whichis released as heat.Energy transfer. When twoobjects at different temperaturesare in contact, heat flows fromthe hotter to the colder object.
  • 4. microwavesElectromagnetic energylightThis is energy storedin electromagneticwaves or radiation.television wavesradio waves
  • 5. Mechanical energyThis is the combination oftwo energies:• kinetic energy• potential energy
  • 6. Mechanical energyThe blocks have potential energy.The falling block has kinetic energybut is losing its potential energy asit falls.The blocks have neitherpotential nor kinetic energy.This is the combination oftwo energies:• kinetic energy• potential energycrane
  • 7. SunNuclear energyenergyThe nucleussplits into twoor more parts.Nuclear fusion energyNuclear fissionThe nucleusjoins toother nuclei.Nuclear power stationAtomic explosionThis is energystored in thenuclei of atoms.
