Link to term
In plain language

How quickly an angle changes with time.

Technical definition

Angular speed is magnitude of angular velocity; rad/s connects naturally to tangential speed and rotational power.

Units
radian per second (rad/s)
Formula
ω = dθ/dt; v = rω

Example 3000 rpm is about 314 rad/s.

Common misconception rpm and rad/s cannot be substituted without conversion.
