The resistance a spinning object shows when you try to tilt it.
What it is
A spinning mass resists changes to the direction of its axis. Tilt a spinning fidget and you feel it push back or move sideways, an effect known as gyroscopic precession.
Why it matters
That tug is part of the appeal: it makes a spinner feel alive in the hand. Heavier, rim-weighted and faster-spinning parts produce a stronger effect.
Also known as: Gyro Effect, Gyroscopic Precession, 回转效应.
是什么
旋转的质量会抵抗其转轴方向的改变。让正在旋转的玩具倾斜，会感到它在“顶”你或往侧面走，这就是陀螺进动。
为什么重要
这种拉扯感是乐趣的一部分，让陀螺在手里像是“活的”。越重、越偏外缘配重、转得越快，效果越明显。
又称：Gyro Effect、Gyroscopic Precession、回转效应。
