Applications  "Really, we can speak only through our paintings." - Vincent Van Gogh     There are many applications of drawing in physics. Not only is drawing one of the best tools for the brain when it comes to understanding a concept, but drawing also is a way of communication that requires very little verbal communication. Therefore, drawing is a key part in understanding the world of science.     A very commonly used application of drawing used in physics and engineering is the free-body diagram or the force diagram. A free body diagram is a system depicted as an image. The main purpose of a free body diagram is to simplify the system to display the forces acting upon it, and therefore is an extremely handy tool when computing said forces. http://ap.smu.ca/demos/index.php?option=com_content&view=article&id=80&Itemid=85 Intro
