angular acceleration : ウィキペディア英語版 | angular acceleration
Angular acceleration is the rate of change of angular velocity. In SI units, it is measured in radians per second squared (rad/s), and is usually denoted by the Greek letter alpha (''α''). == Mathematical definition ==
The angular acceleration can be defined as either: : , or : , where is the angular velocity, is the linear tangential acceleration, and , (usually defined as the radius of the circular path of which a point moving along), is the distance from the origin of the coordinate system that defines and to the point of interest.
