    Force Integral
AI Thread Summary
The discussion centers on the physical interpretation of the L2 norm of force along a path, specifically the integral of the force squared. It is established that the path integral of force corresponds to work, which has a clear physical significance. The inquiry explores whether paths that minimize the L2 norm of force can be characterized similarly to those that minimize work. Clarification is provided on the mathematical representation of the L2 norm, emphasizing its relevance in understanding force dynamics. The conversation highlights the potential for deeper insights into the relationship between force and path optimization.

The path integral of force is the work, something that has a clear physical meaning we can relate to. My question is, what is the physical interpretation for the L2 norm of the force along a path? (integral of the force squared, basically):

\left(\int_\Gamma F \cdot F \right)^{\frac{1}{2}}

If a particle takes the path from point A to B which minimizes the work, then the least amount of external energy was expended moving it from point A to B. Can we analogously characterize the type of paths between 2 points that minimize the L2 norm of the force.

Thanks!

Do you mean:

\left(\int_\Gamma (\mathbf{F} \cdot \mathbf{F})ds \right)^{\frac{1}{2}}

?
 
Yes, of course. F:R3->R3, \Gamma:[0,1]->\textbf{R}^3
 
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
