\subsection{Angular Momentum}  Angular momentum for a particle is described by the equation $L=r \times p$, where $r$ is a vector from the center of rotation to the object, and $p$ is the linear/translational momentum described in the section above. This vector cross product produces another vector which is perpendicular to both $r$ and $p$. In the diagram below, $L$ points out of the computer screen towards the viewer. If the rotation was clockwise instead, $L$ would point away from the viewer. In this way, angular momentum is different to normal momentum as the vector describes the axis that the object is rotating around instead of the direction it is travelling.  $im dead$
