"Work done by the electric field"

AI Thread Summary
The term "work done by the electric field" refers to the integral of force over distance, represented as ∫F.dL, which some argue should instead be termed "work done by the electric force." The discussion highlights the ambiguity in terminology, suggesting that language evolves based on tradition rather than strict logic. Participants acknowledge that while the terminology may frustrate some, it is widely accepted in physics. The work done is influenced by the sign of the test charge and the direction of the electric field, which affects the force's direction. Ultimately, the conversation emphasizes the importance of understanding the concepts rather than getting caught up in the terminology.

Why is ∫F.dL called the work done by the electric field? This makes absolutely no sense in my opinion, and I think it should be called the work done by the electric force.

∫E.dL should be called the work done by the electric field. Even if that's not rigorously "work".

Can anyone prove me wrong so that I stop feeling pissed off when I do problems?

Thanks.

Its english. English, like all natural language, arises organically and is not subject to strict rules of delineation and logic. That is one reason math was invented in the first place.

Might as well get all pissed that you drive on the parkway and park on the driveway.

No.

But much of natural language is <understatement>less than completely precise</understatement> and the terminology has evolved over time and is driven by tradition as much as logic... So it is the way it is. The only person who gains when you get pissed off is your cardiologist.
 
Lol. I laughed at that cardiologist thing. So just to be sure, whenever they say work done by the electric field they really just mean the work done by the electric force right? Like, it will depend on the sign the test charge has right?

Yes. The sign of the test charge and the direction of the field determine the direction of the force, so if you change one but not the other you change the direction of the force.
 
Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
