✔ 最佳答案
The pointer is connected to a soft spring. When it is deflected, it overshoots the right position. The spring then provides a restoring force trying to return it to the right position. Hence, an oscillation is produced.

The oscillation eventually stops because of friction.

好多meter個Pointer另一端有阻尼,可以增加friction
