Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific principle?Self-excited vibration leading to resonant oscillation
2. What is the frequency range?4–10 Hz, a critical range for resonance in many vehicle dynamics
3. Why does a speed wobble happen?It happens when the steering system doesn’t have enough damping, so small bumps can grow into big shakes. The wheel’s movement feeds back into the steering and makes the wobble get stronger.
4. How can I stop a speed wobble?Slow down smoothly and avoid sudden turns. Keeping the steering steady helps the wobble stop.

Self-excited vibration: A vibration that is sustained by energy extracted from a fluid flow or relative motion.
Eigenvalue analysis: A mathematical method used to determine the stability and dynamic behavior of a system.
Yaw oscillation: A rotational movement of a vehicle around its vertical axis, causing side-to-side swaying.
