Presentation Transcript

  1. KS4 Energy transfers

  2. Transducers change energy from one form to another electrical kinetic light electrical elastic kinetic electrical light

  3. Transducers 2: electrical sound electrical sound kinetic gravitational electrical kinetic

  4. Transducers 3: heat electrical elastic kinetic heat chemical electrical kinetic

  5. Transferring energy “Energy can neither be created or destroyed, just changed in form.” You need to be able to give examples of devices that perform specific energy changes. You need to be able to describe the energy changes for a given device. You need to remember that whenever energy is changed from one form to another, some energy is always wasted.

  6. Television What are the main energy transfers for a television (don’t forget the wasted energy)? light sound electrical heat

  7. Car engine What are the main energy transfers for a car engine (don’t forget the wasted energy)? kinetic sound chemical heat

  8. Radio What are the main energy transfers for a radio (don’t forget the wasted energy)? sound heat electrical

  9. What is the intended energy transfer for a Bunsen burner? • Sound  light • Heat  chemical • Chemical  light • Chemical  heat 

  10. What is the energy change for a falling rock? • Kinetic  gravitational • Gravitational  kinetic • Kinetic  speed • Mass  speed 
