Mo9-L1b: How are Energy and Work Related?




        In every energy transformation and every energy
        transfer, some energy is transformed into thermal
        energy.

























        This thermal energy is transferred to the surroundings.

        Thermal energy moving from a region of higher
        temperature to a region of lower temperature is
        called heat.


























        Scientists sometimes call this heat waste energy
        because it is not easily used to do useful work.



                          SUMMARY
                How are Energy and Work Related?
                 Work and energy are related.
