This GeoGebra app shows how angular velocity *ω* is the rate of change of angular displacement (i.e. $\omega=\dfrac{\theta}{t}$) and is dependent on the speed and radius of the object in circular motion (i.e. $v=r\omega$).

Students can explore the relationships by doing the following:

Keeping *r* constant and varying *ω*.

Keeping *ω* constant and varying *r*.

Keeping *v* constant by varying *r* and *ω*.
