Web17 dec. 2014 · -1 Given a path C and a force field F, the work done on the particle can be found by ∫ C F → ⋅ r → d r This seems to suggest that you can find the work done for any path. Doesnt the path depend on the force field? So given F, there is a limited range of paths. (Depending on starting position, velocity, mass) vector-fields Share Cite Follow
