Homework Help: Differences between delta W or dW

  1. Aug 16, 2007 #1
    Why in some sites, the work appears like [tex] \ \ \delta W[/tex] instead of dW ?

    Whats the differences between [tex] \ \delta W[/tex] and dW?


    thanks

    [tex]\delta W[/tex] refers to a small, but "real" change in W. dW is the differential and actually refers to a limit. The way this is used in physics it really should be [tex]\delta W[/tex] but many writers 'bend" the meaning a little and use dW.

    in some case [tex]\delta W[/tex] refers to work done by force such that it is exact differential
