 $$Work = (Force)*(distance) = (Newtons)*(meters) = Nm = Joule$$
-The units of work is a Joule named after [[http://en.wikipedia.org/wiki/James_Prescott_Joule|James Joule]], an English physicist and beer brewer. One Joule is equal to 1 $Nm$ or 1 $kgm/s^2$.

 What's very interesting about the work done by the local gravitational force is that it is //[[http://en.wikipedia.org/wiki/Conservative_force|conservative]]//. The work done by the gravitational force does not depend on the path the object takes, only on the initial and final location of the object, which is how conservative forces are defined. In particular, it only depends on the change in the vertical position of the particle. That's all that matters for conservative forces -- the end points.
