I'm currently taking a college level physics course, and I'm struggling with the idea of angular momentum, whereas linear was fairly intuitive I guess something seems amiss when trying to understand rotational applications. Lets take the idea of a spinning wheel. The direction of angular momentum is a cross product giving it a direction perpendicular to the wheel this seem odd as no component of the wheel is moving in this direction. I've seen applications like gyroscopes but I guess I don't really understand, If anyone has anything to help explain angular momentum it would be appreciated. This is a first post, I've really been quite taken with physics since enrolling in this class, and this forum appears to be a gold mine of resources. Thank you in advance.
