Conservation of Angular Momentum

(chapter 4)

Angular Momentum is defined as the moment of the Linear Momentum about some spatial reference point. Thus, it is the vector cross product with the linear momentum.
angular momentum = linear momentum
Like linear momentum, angular momentum is conserved.

Thus, like conservation of linear momentum, we have the same spatial and time derivatives; except they operate on the angular momentum. Recall conservation of linear momentum for a differential system as shown below:
