an·gu·lar ac·cel·er·a·tion

the rate of change of angular velocity; for example, when a centrifuge rotor is speeding up, or when there is a simultaneous change in velocity and direction, as in an aircraft in a tight spin.

angular acceleration

Rate of change in velocity per unit of time during circular movement.

We designed an experiment to determine the maximal angular acceleration of the human head.
Preliminary but more attentive reference to NASA data allows noticing that observed angular acceleration of the probes too could significantly incorporate to values of "relativistic deceleration".
We termed the acceleration phase as the time lag between the moment when the angular acceleration of the trunk rotation became maximal to ball release, and post ball release from ball release to the end (100ms after ball release).
r] are the reduced driving moment and the reduced moment of resistance forces; [epsilon], [omega], [phi] are the angular acceleration, angular velocity, and rotation angle of the reduction link; [J.
For example, in tunnels or narrow valleys, positioning information can be fed to the STA2051's inputs by taking advantage of the sensors, such as an odometer for velocity and forward or backward movement, and an angular acceleration sensor, such as a gyro or ABS sensor, as a directional indicator.
In particular, during an isoinertial resisted joint mobility test, an IMU fixed on the rotating body segment could be used to simultaneously estimate both the angular displacement and the angular acceleration of the segment: the first can be considered representative of joint ROM, while the second can be considered the result of a joint torque produced by the action of muscle forces.
