When in an electron field, say a proton is in a fixed locationIf an electron was fired at it with a certain velocity from a great distance away, it would accelerate towards itThis acceleration would cause a increase in the kinetic energy of the electron.Since all energy is conserved, where is this addition to the energy at the initial time? And how would 1 go about calculating this?
A very interesting question! It took work to get the electron away from the electric field in the first placeIt is sometimes very hard to imagine where energy comes from and what does the workFor exemple, a magnetic force can not do any work, it is however sometimes very hard to understand what does the work (for example if a crane lifts a car using a magnetic force)This is, I think, the reason why some amateure scientists are still looking for a perpetuum mobile.
