    Energy can be described as being in different 鈥榮tores鈥. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

  • Work, power and efficiency - AQA

    Energy is a key principle in physics, as it allows work to be done. The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.

  • Energy and heating - AQA

    Energy is transmitted by conduction, convection or radiation.The conductivity of materials can be compared by examining the time taken to transmit energy through them.

  • Energy demands - AQA

    Every person, animal and device transfers energy. Much of that energy is supplied by electricity, which must be generated from other energy stores. Some of these are renewable but most are non-renewable.
