Introduction to Statistical Thermodynamics - cryocourse 2011
... Note that the symbols δQ and δW indicate that Q and W are infinitesimal. This does not correspond to the “variation” of any “function” Q or W. There is no heat “after” or “before” the interaction. There is heat and work associated to the process of interaction, not to the initial and final states. ...

LECTURE 26: Work- Kinetic Energy
... This interpretation of the work-energy theorem states that "take the initial kinetic energy of the system and add it to the net external work being done on the system, this addition is equal to the final kinetic energy of the system". It is very important to note, that energy and work are both scala ...

... Sand is now removed, “one grain at a time” allowing the gas to expand in infinitesimal steps, continually passing through equilibrium states. Moreover, it is conceivable that at any point a single grain of sand could be returned to the pile and exactly restore the previous equilibrium state. Such a ...

work, energy, and simple machines
... In physics, that expended energy means a force was applied. There is not much difference between work and energy. In order to do work, an object must have energy In order to have energy, an object must have work done on it. ENERGY - the measure of a system's ability to do work. Energy is classif ...
