Notes pb lab 01c energy transformations 2 vocabulary notes

  1. 1. Notes
  2. 2.  Thermal EnergyChemical EnergyElectrical EnergyRadiantNuclearMechanical
  3. 3.  Energy created from themovement of molecules (kineticenergy) The faster the particles move thegreater the energy and the greater theobjects thermal energy▪ Example: Steam Engine
  4. 4. ▪Energy created as the atoms of asubstance are rearranged througha chemical reaction.▪Can be a form of potential energydepending on the position andatomic arrangement▪Example: BatteriesWet /Chemical Cell/ or Dry Cell
  5. 5. Energy created through themovement/flow of electrons.(current)▪Measured in volts and amperes▪Example: Electricity
  6. 6. Energy that radiates out from asource.▪ Is considered a form of kinetic energy▪ Produced by vibrations of electricallycharged particles coming from a source (sun.lights, heater) that travels in waves calledtransverse wavesExample: Sunlight(Electromagnetic Radiation)
  7. 7. Energy created from thecombining of the nuclei or splittingof the nucleus of an atom:▪Two types▪Fusion (Combining)▪Fission (Splitting)
  8. 8. ◦ The Energy of/in motion◦ Can be classified as either potentialor kinetic depending on thecircumstances.◦ If its moving, then it is mechanicalenergy!
  9. 9. ◦ When an object is at rest it haspotential mechanical energy◦ Ball at top of ramp (Potential)◦ When an object is in motion it haskinetic mechanical energy.◦ Car moving down the road (Kinetic)
  10. 10.  Get together with your lab partner and go tothe workstation that corresponds with yourtable number. Follow the directions for the lab beginning onpage 2. Complete Page 2 Go to your seats to complete page 3 If you complete page 3, read page 4 and beginto research Nuclear Energy in your textbooksand begin page 5.
  11. 11. Energy is the ability to do work orcreate change
  12. 12. There are 2 major categories ofenergyPotential Energy – Stored Energy▪Ex. Batteries, Tank of gasKinetic Energy – Energy in Motion▪EX. Car Moving, Bowling Ball Rolling
  13. 13. There are 6 basic forms of energy Radiant Thermal Chemical Electrical Mechanical Nuclear
  14. 14.  An energy chain is a tool used to describehow energy changes as it moves along theline It identifies each type of energy as ittransforms from one form to another
  15. 15. Energy SourceA term used to identify where theenergy chain begins or where theenergy comes from
  16. 16. Energy ReceiverA term used to identify where theenergy chain ends.In many cases YOU are thereceiver
  17. 17. As energy transforms from one formto another, some of the energy islost as heat, but energy is nevercreated or destroyed under ordinarycircumstancesThis is called The Law ofConservation of Energy
  18. 18. Nuclear Energy Two types▪ Fission :▪ Splitting the nucleus of an atom▪ We can perform fission on earth▪ Fusion:▪ Combining the nuclei of two or more atoms▪ Done in the Sun
