\label{Variable_Naming_Conventions} There are many variable naming conventions, covering both how to name and how to capitalize variables% \footnote{The author favors \texttt{capsOnNewWords}. Some people use \texttt{underscore\_to\_separate\_words}. Many use uppercase letters to specify constants like \texttt{PI} or \texttt{GOLDEN\_MEAN}. Some people always \texttt{StartWithCapatalization}. What's really important is to be consistent, so you don't have to guess whether the variable you're thinking of is \texttt{coefFriction}, \texttt{CoefFriction}, \texttt{COEF\_FRICTION}, or something else.% }. It is a good idea to adopt a standard. If you are working with a group, you may wish to discuss it in your group and agree on a convention.
