comment Why does kinetic energy increase quadratically, not linearly, with speed?
This can expanded by demanding that the Lagrangian give rise to invariant equations of motion under Galilean transformations. If you do this you find it must depend on v^2.

No. Energy can also be transferred as heat.

comment Why does the fundamental mode of a recorder disappear when you blow harder?
Thanks for the work and the references! Haven't read in detail yet, but look forward to it.

comment Energy Gain with capacitor?
No. If you take any trajectory the electron could follow, as long as the trajectory starts far away and ends far away, the path integral of the electric field dotted with a tangent to the trajectory will be zero.

comment Energy Gain with capacitor?
If you try really hard, and pick one particular special point, then yes you can find one point where the velocity and field are perpendicular. Trace the path a little further and they won't be. Yes, you could repeatedly send electrons through the capacitor. Each one would speed up then slow down again.
