Angular velocity means not how many meters per second but how many radians per second.

角速度不是指每秒经过的路程，而是指每秒经过的弧度。

And angular acceleration is the derivative of angular velocity.

角加速度等于，角速度的导数。

Remember angular velocity is just the rate of the change of the angle over time.

角速度,是角度随时间改变的快慢。

They also calculated impact dose injury risk parameters common to laboratory and on-field traumatic neuromechanics: linear acceleration, angular acceleration, angular velocity, Gadd Severity Index, diffuse axonal injury, acute subdural hematoma, and brain contusion.

Freespace Sensor Modules are used by engineers to add inertial motion control to a product without having to learn about motion sensing or MEMS. These compact modules, the smallest of which is 9mm x 19mm x 2.5mm, are pre-calibrated for mass production, provide a well-documented API for interpreting motion, and provide data such as cursor position, linear acceleration, angular position, and angular velocity to enable the creation of novel applications.
