We define and discuss how to draw Free Body Diagrams which are also called Force Diagrams. In addition we define the force normal and the force applied. Force of friction and center of mass are briefly discussed, however, a much more detailed discussion of each is left for later lessons. Free Body Diagrams are drawn on a level surface and on an incline.
