ok i collected the common terms in i j k so i understand that but when i try to find the work (w = -(change in potential) i get 0.

ok so the grad of F is the partial with respect to x,y,z. so if f is the gradient i need to indiviually integrate i j k with respect to x y z.

ok let me try that then.

almost forgot i have to integrate this dot porduct but that shouldn't be too hard.

yea i have been working on other problems since i wasnt sure how to start this one. But i did the dot product and for my function i got. 2*((2xyz-z^3)+(2x^2z)+(x^2y-3xz^2). stop me if I am wrong here but the rest should be: part b looks like i just use (1,2,1) and plug them into my potential...

they didnt specify. but I am assuming that the curl is 0.

Homework Statement 1. Given F = -2 N/m^3 ( (2xyz - z^3)i + x^2z j + (x^2y - 3xz^2)k ). a. Find the potential energy function for this force, taking (i + 2 j + k) m as reference point. b. Find the work done by this force on a 4-kg block moved from the reference point to the origin. c...
