Work as the Dot Product
Work as the dot product is defined. The dot product using unit vectors is reviewed. Several examples are worked through. Want Lecture Notes? http://www.flippingphysics.com/work-d...

This means I switched which vectors have components of zero in the j and k directions. The force vector has no component in the j direction. The r-position vector has no component in the k direction. Sorry about that!!
