... First we define the work done by a force, both in the case where the force is constant and the motion is linear, and in the general case in which the force is variable and the motion is curvilinear. Different persons or different machines may take different amounts of time to do the same amount of w ...

Chapter 19 The First Law of Thermodynamics
... energy U of a system is equal to the heat added minus the work done by the system: U = Q – W. The first law of thermodynamics is just a generalization of the conservation of energy. Both Q and W depend on the path chosen between states, but U is independent of the path. If the changes are in ...
