In this video, we explain the conservation of angular momentum in AP Physics 1, showing why angular momentum remains constant and how it applies to rotating systems. You’ll see clear examples that ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

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 ...

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 ...

The manoeuvre depends on the principle of conservation of angular momentum, which states that the angular momentum of a system remains constant unless external torques act on it. For example, some ...
