Unformatted text preview: 106 Chapt. 12 Rotational Dynamics is a quantity we define as a measure of rotational motion about a point or axis. The cross product in the definition is very useful in making angular momentum a measure of rotation. If a particle is moving directly away from the origin, then its not rotating about the origin in any common-sense sense and the cross product reflects this by giving angular momentum. If a particle is moving perpendicularly to a line to the origin, then it could be rotating about the origin and even be in circular motion about the origin and the cross product reflects this by giving angular momentum magnitude for the given magnitudes of displacement and momemtum. a) zero; infinite b) the maximum; infinite c) no; zero d) the maximum; zero e) zero; the maximum 012 qmult 00315 1 1 3 easy memory: v X mv=0 6.
