Here is a khan academy video on finding the work needed to move a charged electron in a electric field. The only catch is he is doing it in Calculus!! Looking at it for some reason it seemed easier to derive an answer using the true calculus method. But I'm going to stick to my handy equation sheet and trust in C-Rod's methods. Just don't understand why Khan makes it look so EASY! ugh

This website took a more theory and concept approach perse. It did not show much for numbers but the idea of what to expect from these charged particles, do I find this useful? Yes to a certain extent but do not feel it will help me much in my classroom.
