This lecture on path independence and conservative fields help sum up the ideas from the previous lecture and push into a slightly different way of looking at a similar topic. Mostly, example problems are shown in this lecture. Sometimes, fields are path independent and conservative, and other times, they are not. This is discussed in some depth along with gradient fields.
