Angular radius equals half of the angular diameter. Angular acceleration is the time rate of change of angular velocity. The symmetry associated with conservation of angular momentum is rotational invariance. Rheometers and viscometers work with torque and angular velocity. This is determined based upon the inertia of the flywheel and its angular velocity. Typical servos can give a rotary (angular) or linear output. This is as desired for equally spaced angular momenta. It supports strict conservation of linear and angular momentum. The women appear slightly menacing and are rendered with angular and disjointed body shapes. Torque can be defined as the rate of change of angular momentum, analogous to force. Corresponding global definitions exist for momentum and angular momentum. This is a direct result of the addition rules for quantized angular momentum. Infrared thermometers are characterized by specifications including accuracy and angular coverage. Its dimension is the same as that of an angular momentum. This prevents the existence of a hydrodynamic mechanism for angular momentum transport.
