Angular velocity is the rotational equivalent of translational velocity. There are a number of kinematic equations for angular motion which are entirely analogous to the linear motion equations, such as w? + 2aA0 compared with = v? + 2aAx. These equations are valid only when: O a there is no torque. b. the angular acceleration is constant. C. there is no moment of inertia. d. there angular displacement is 0.

there is no torque.
b. the angular acceleration is constant.
С.
there is no moment of inertia.
d. there angular displacement is 0.
e. there is no angular acceleration.
