ANGULAR VELOCITYANGULAR VELOCITY is the Physical quantity derived from base physical quantity defined as - " Angular Velocity is rate at which angular position of a body changes w.r.t chosen point centre "
By convention positive angular velocity indicates counterclockwise rotation why negative is clock wise.
Conventionally angular velocity as specified by Right Hand Thumb Rule.
Angular velocity determined by formulae
Where , V prependicular is cross radial component of v .
Hence, According to Right hand thumb rule
According to left Hand Thumb Rule
