The angular momentum of a flywheel having a rotational
inertia of 0.140 kg m2 about its central axis decreases from
3.00 to 0.800 kg m2/s in 1.50 s. (a) What is the magnitude of the average
torque acting on the flywheel about its central axis during
this period? (b) Assuming a constant angular acceleration, through
what angle does the flywheel turn? (c) How much work is done on
the wheel? (d) What is the average power of the flywheel?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
