Question

Quizplus · Accepted Answer

Angular momentum is a property of rotating objects or systems, where the amount of momentum depends on the mass, velocity, and distance from the axis of rotation. The navigation equipment on airplanes, the hubcap and tire system on an automobile, a figure skater's spin, and a satellite in outer space all involve rotating objects or systems and therefore demonstrate angular momentum. The apple falling from a tree, however, does not involve rotation and therefore does not demonstrate angular momentum.
