This lesson will review work by a force and how to look at a box that is being pulled by a force and how and why to multiply by a cosine of an angle between the force and the displacement. The components that do the work will be shown and explained through an example and diagram of how to find the work done by force by finding the parallel component of the force, the parallel force to the displacement multiplied by cosine of the angle that is parallel component and the displacement.
