The linear​ speed, v, of a point a distance r from the center of rotation is given by v=​, where ω is the​ speed in radians per unit of time. The linear​ speed, v, of a point a distance r from the center of rotation is given by v= ▼ r omega commarω, StartFraction r Over omega EndFraction comma r ω, StartFraction omega Over r EndFraction comma ω r, where ω is the ▼ angular linear total speed in radians per unit of time.
