Detailed Instructions: Given a scientific passage and an answer, generate a question for the given answer.
Q: Passage: This same logic explains the behavior of gyroscopes. Figure 10.31 shows the two forces acting on a spinning gyroscope. The torque produced is perpendicular to the angular momentum, thus the direction of the torque is changed, but not its magnitude. The gyroscope precesses around a vertical axis, since the torque is always horizontal and perpendicular to L . If the gyroscope is not spinning, it acquires angular momentum in the direction of the torque ( L falling over just as we would expect. Answer: torque
A:
If a gyroscope is not spinning, it acquires angular momentum in the direction of what?
