Angular acceleration

Japanese: 角加速度 - かくかそくど(英語表記)angular acceleration
Angular acceleration

The rate of change of angular velocity over time, or the rate of change. In the SI system, it is expressed in radians per second per second (rad/ sec2 ). If the angular velocity when the angle changes by in an infinitesimal time dt is ω, then ω= / dt , and the angular acceleration β is

In the equation of motion for rotational motion, this is often expressed as β.

角速度の時間的変化の割合、変化率。SI単位系ではラジアン毎秒毎秒(rad/sec2)で表示される。微小時間dtの間に角度がdθだけ変化するときの角速度をωとすると、ω=dθ/dtであり、角加速度βは

である。回転運動の運動方程式ではβと表示されることが多い。
