Question

Quizplus · Accepted Answer

Precession is the rotation of an angular momentum vector around a vertical axis. It is often described as the wobbling motion that occurs when a spinning object experiences a torque that is not parallel to its axis of rotation. This causes the angular momentum vector to move in a circle around the axis of the torque, resulting in precession.
