Transcript

  • 1. WHAT ISENERGY
  • 2. Is the ability or capacity to do work .It used to do some kind of work.
  • 3. is active, moving andis being used. It isenergy in motion.
  • 4. Is energy waiting to be useddue to its position orcondition.
  • 5. OTHER FORMS OF ENERGY MECHANICAL ENERGY CHEMICAL ENERGY THERMAL ENERGY SOUND ENERGY RADIANT ENERGY ELECTRICAL ENERGY NUCLEAR ENERGY LUMINOUS ENERGY
  • 6. is the energy that is possessed by an objectdue to its motion or due to its position.Mechanical energy can be either kineticenergy (energy of motion) or potential energy(stored energy of position).
  • 7. is energy stored in the bonds of atoms andmolecules. Batteries, biomass, petroleum,natural gas, and coal are examples ofstored chemical energy. Chemical energyis converted to thermal energy when weburn wood in a fireplace or burn gasoline ina cars engine.
  • 8. or heat, is the vibration and movement ofthe atoms and molecules within substances.As an object is heated up, its atoms andmolecules move and collide faster.Geothermal energy is the thermal energy inthe Earth.
  • 9. is the movement of energy through substancesin longitudinal (compression/rarefaction) waves.Sound is produced when a force causes an objector substance to vibrate — the energy is transferredthrough the substance in a wave. Typically, theenergy in sound is far less than other forms ofenergy.
  • 10. is the energy of electromagnetic waves. Thequantity of radiant energy may be calculatedby integrating radiant flux (or power) withrespect to time and, like all forms of energy, its SIunit is the joule. The term is used particularlywhen radiation is emitted by a source into thesurrounding environment. Radiant energy maybe visible or invisible to the human eye.
  • 11. is delivered by tinycharged particles calledelectrons, typically movingthrough a wire. Lightning isan example of electricalenergy in nature, sopowerful that it is notconfined to a wire.
  • 12. is energy stored in the nucleus of anatom — the energy that holds thenucleus together. Very large amounts ofenergy can be released when thenuclei are combined or split apart.Nuclear power plants split the nuclei ofuranium atoms in a process calledfission. The sun combines the nuclei ofhydrogen atoms in a process calledfusion.
  • 13. is the perceived energyof light. This is sometimescalled the quantity oflight. Luminous energy isnot the same as radiantenergy, thecorresponding objectivephysical quantity.
  • 14. THE END!!!!!!THANKYOU!!!!!!!
