I think the issue with work being a scalar is mathmaticlly solved by szimmy below;
This is the correct equation rather than the Wnet=W[a]-W[f] that I wrote. By using the forces the direction can be correctly accounted for.
Thanks everyone for your input!
I think my confusion has more to do with the english langauge than the physics involved.
--So the net force is the difference between applied force and the force of friction.
--This net force leads to a net work.
--A net force→net work→leads to an...
I am looking for some clarity on what should be general conceptual questions involving work, net work, and work done by friction. In General;
W[F]=the component of the applied force acting in the direction of motion X distance OR
W[friction]=μN and is...
