Some students interpret conservation to mean energy must reappear in its original form

Energy and Thermal Physics

Misconception RESEARCH REVIEW

Many students also reason that energy will be lost in physical processes, (even those who recognise the principle of conservation of energy).

Resources to Address This

  • Shifting and conserving energy (11-14)

    Ref - SPT En02 PN08

    This resource involves discussion of lifting an object

    1. Can emptying the second store (associated with the ornament in a higher position) do an equivalent job to that done by emptying the first (the chemical store associated with the muscles of your arm)?
    2. If not, what happens to the energy not shifted from the first store to the second?
    3. Is it possible to reduce this shortfall?

    After establishing the energy transfer, it is necessary to introduce the idea of energy dissippation into the surrounding environment.
