For the general case. I need help finding the cross product for the angular momentum. Say you have a particle at a position r= xi+yj+zk with a velocity of xi+yj+zk and a known mass. How do you find the angular momentum?
The Attempt at a Solution
So I know how to find the cross product of r and v. It will be some xi+yj+zk. Then how do you find the angular momentum from there?
