### Lecture 5

in lecture 5 you state that the enetgy changr can be in the form of equation (2). i donr really understand way this is the change due to the electrodynamic force, irs look like summing up all the forces in that volume - not the change.

I am summing the works per unit time done on all particle which would give the rate of the change of the total energy of these particles
