Stating an equation in words doesn't explain its origin.

P = F/a = F/d^2
V = d^3

P is force, but V is definitely not distance. P isn't really force either, so your explanation doesn't make logical sense.

Going from the above equations, using simple algebra, only PV will give the solution W = FD, which is what I understand to be the definition of work. However, I'm not interested in the algebra; I'm interested in the calculus behind this equation. In calculus, W = FD isn't really W. It's dW. Which leads to my original question, why the VdP term is not in the equation for dW.

And if dW is work, what is W=integral(dW)?
