Energy stores & systems

• Give 4 ways energy can be transferred

  1. Mechanically
  2. electrically
  3. through heating via infrared radiation
  4. via light or sound waves
• What do we mean by thermal energy store?


  Heat stored in an object.
• What do we mean by elastic potential energy?

  Energy stored in a stretched or compressed object.
• What do we mean by magnetic energy store?

  Magnetic field storing energy.
• Name the 8 energy stores

  1. Thermal
  2. gravitational potential
  3. elastic potential
  4. magnetic
  5. chemical
  6. electrostatic
  7. nuclear
  8. kinetic
• What do we mean by gravitational potential energy store?


  Energy stored in an object due to its position in a gravitational field.
• What do we mean by electrostatic energy store?

  Energy stored when repelling charges have been moved closer together or when attracting charges have been pulled further apart
• What do we mean by kinetic energy store?


  Energy stored in an object due to its motion.
• What do we mean by nuclear energy store?

  Potential energy stored in the nucleus of an atom.
• What do we mean by chemical energy store?

  Potential energy stored in chemical bonds.
• As an object falls, which energy stores does energy pass between?

  Gravitational potential energy to its kinetic energy store
