Angular speed is the rate of change of which quantity?

Explanation:
Angular speed tells you how fast the orientation around the rotation axis is changing over time. It is defined as ω = dθ/dt, where θ is the angle (measured in radians). So the quantity whose change defines angular speed is the angle itself. For example, rotating through 2π radians in one second gives ω = 2π rad/s. This is different from how quickly linear speed changes (that’s tangential acceleration) or how the radius or mass changes, which aren’t what describe angular motion.
