$W = \int\limits_{a}^{b} F(x)d(x)$ Is a closed path is always zero why is that?

2. Hope99

Well work done by gravity that is...

I can imagine that gravity does no work because the start & endpoint is the same. |dw:1365011587034:dw|

Um. The distance did not change I guess, so the work = F x 0 = 0?

only by conservative forces.. . :)

and independent of the path followed.
