  1. Energy Transfer D. Crowley, 2008

  2. Energy Transfer • To understand energy transfer, and to be able to show this in a diagram

  3. Energy • What types of energy are there? • Electrical energy - a current in a circuit etc… • Light energy - from the sun; a light bulb etc… • Sound energy - from a loudspeaker; a drum etc… • Kinetic (movement) energy - anything which moves! • Nuclear energy - transferred during a nuclear reaction • Thermal (heat) energy - transferred from hot objects to colder ones • Radiant heat (infra red) energy - transferred as electromagnetic radiation by hot objects • Gravitational potential energy - possessed by anything with the ability to fall • Elastic potential energy - stretched springs; elastic and rubber bands etc… • Chemical energy - possessed by food; fuels; batteries etc…

  6. Created & Destroyed • Energy is the ability to ‘do some work’ - everything that happens needs energy • However, energy cannot be created or destroyed, only transferred from place to place in a variety of ways

  7. Waste • When energy is transferred from one type to another there is often ‘wasted’ energy • This ‘wasted’ energy is in a form which you do not want • E.g. what is the wasted energy in a circuit which lights a bulb? • In a circuit chemical energy (within the battery) is transferred to electrical energy which runs through the circuit to light energy in the bulb • However, heat from the current in the wires / when the bulb is on is our ‘wasted’ energy

  8. Energy Transfer • Your task is to go to each of the stations and record the initial energy (where the energy comes from); what useful energy transfer(s) the device gives; and what non-useful energy transfer(s) there is
