My textbook says that work done by a conservative force is independent of the path taken. This tells me that ##\int_{a}^{b} \vec{f} \vec{dl} ## only needs displacement (not distance) between points a and b. Conservative, according to my book, means that there is no friction. I have difficulty conceptually understanding this. Of course I'll feel more tired if I move a block of ice in a complicated path than if I did a straight line. Thank you.
