Final answer:

Angular acceleration is the rate at which an object's angular velocity changes, crucial in analyzing rotational motion.


Explanation:

Angular acceleration is the rate at which an object's angular velocity changes over time. It is a measure of how quickly the direction and speed of rotation of an object change.

  • For example, when a figure skater spins, they accelerate by increasing their rotational speed, showcasing angular acceleration.

Understanding angular acceleration is crucial in analyzing rotational motion and determining how quickly an object is changing its rotational speed and direction.
