Energy stores and systems

• Energy can be stored as:

  • Kinetic
  • Thermal
  • Chemical
  • Nuclear stores
• What are energy stores related to an object's position in a field or its deformation:

  • Gravitational potential energy
  • Elastic potential energy
  • Electrostatic stores
  • Magnetic stores
• How is energy transferred from one store to another?

  • Mechanically
  • Electrically
  • Heating
  • Radiation (including light or sound energy)
• What does the rate of transfer of energy depend on?

  • Differences in temperature between the heat source and the object
  • Properties like the objects material or surface area
