types of energy stores

• Energy is never used up. Instead it's just transferred between different energy stores and different objects
• Energy transfer


  When energy is transferred to an object, the energy is stored in one of the object's energy stores
• Energy stores


  • Thermal energy stores
  • Kinetic energy stores
  • Gravitational potential energy stores
  • Elastic potential energy stores
  • Chemical energy stores
  • Magnetic energy stores
  • Electrostatic energy stores
  • Nuclear energy stores
• Energy is transferred mechanically (by a force doing work), electrically (work done by moving charges), by heating or by radiation (e.g. light, p.76, or sound, p.88)
• When a system changes, energy is transferred
• Thermal energy stores are also called internal energy stores
