angular acceleration

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

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.
