Energy created from themovement of molecules (kineticenergy) The faster the particles move thegreater the energy and the greater theobjects thermal energy▪ Example: Steam Engine
▪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: BatteriesWet /Chemical Cell/ or Dry Cell
Energy created through themovement/flow of electrons.(current)▪Measured in volts and amperes▪Example: Electricity
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 wavesExample: Sunlight(Electromagnetic Radiation)
Energy created from thecombining of the nuclei or splittingof the nucleus of an atom:▪Two types▪Fusion (Combining)▪Fission (Splitting)
◦ The Energy of/in motion◦ Can be classified as either potentialor kinetic depending on thecircumstances.◦ If its moving, then it is mechanicalenergy!
◦ 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)
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.
Energy is the ability to do work orcreate change
There are 2 major categories ofenergyPotential Energy – Stored Energy▪Ex. Batteries, Tank of gasKinetic Energy – Energy in Motion▪EX. Car Moving, Bowling Ball Rolling
There are 6 basic forms of energy Radiant Thermal Chemical Electrical Mechanical Nuclear
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
Energy SourceA term used to identify where theenergy chain begins or where theenergy comes from
Energy ReceiverA term used to identify where theenergy chain ends.In many cases YOU are thereceiver
As energy transforms from one formto another, some of the energy islost as heat, but energy is nevercreated or destroyed under ordinarycircumstancesThis is called The Law ofConservation of Energy
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
