If the angular velocity of a body changes, it is said to have an angular acceleration . 如果物體的角速度是改變的,就說這個物體具有角加速度。
For a rigid body rotating about a principal axis, the angular acceleration is related to torque by t =ia . 對于繞主軸轉動的剛體來說,角加速度與轉矩的關系是TIa。
Concerning the dynamic with the discussion for angular velocity and angular acceleration of the rigid body rotation 關于剛體轉動的角速度和角加速度的討論
For a rigid body rotating about a principal axis , the angular acceleration is related to torque by t = ia 對于繞主軸轉動的剛體來說,角加速度與轉矩的關系是t ia 。
It will produce very big angular velocity , angular acceleration and angular jerk when tracking fast moving targets . this may lead bigger tracking error and fail to track targets 目標速度的提高將會產生大的角速度、角加速度乃至更大的角加加速度,導致光電經緯儀電視跟蹤動態誤差急劇增大,目標逸出視場,跟蹤失敗。
Angular acceleration is the rate of change of angular velocity. In SI units, it is measured in radians per second squared (rad/s2), and is usually denoted by the Greek letter alpha (α).
