====== JOINT ACCELERATION and JOINT ANGULAR ACCELERATION ====== || The joint angular acceleration is a vector that describes the relative angular acceleration of one segment relative to another segment. The Joint Angular Acceleration equals the derivative of the [[Visual3D:Documentation:Pipeline:Model_Based_Data_Commands:JOINT_VELOCITY_and_JOINT_ANGULAR_VELOCITY|Joint Angular Velocity]]. {{:JointAccelerationDlg.jpg}}\\ Units= degrees/second^2
