In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...
Let me get rid of the θ and r3 terms where: This gives an angular momentum of: The same as before. So, although the person is moving in a straight line the angular momentum (about that rotation point) ...
This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
