I know the integral to compute work done is
(integral from a to b) F * dl
where F and l are vectors, but I don't understand how I would use that in a problem.
1. Are a and b moments in time?
2. What is dl? Is that the same thing as l2-l1? So would it be (integral from a to b) F(l2-l1) and just integrate that?
Any help would be greatly appreciated. Thanks.
Edit: It would really be helpful if someone could provide a sample problem and explain how to do it that way.
