Which statement about precession is false?
Answer: D
Correct answer: Its rate rises as angular momentum increases
The relation is \( \Omega = T/I\omega \), so precession rate falls as angular momentum rises. That inverse dependence is why a fast heavy rotor makes a stable reference.
The other three statements are true: precession appears 90 degrees from the applied force, in the direction of rotor rotation, and its rate is proportional to the torque. The formula contains both dependencies, and the question tests whether the denominator is read correctly.
