Question

A flywheel is rotating at 20 rev/min and speeds up to 50 rev/min in 90 seconds.
What is the angular acceleration of the flywheel in radians per second squared?
How many revolutions did the flywheel spin during the 90 seconds?

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 .
