Angular Velocity is a measure of how quickly an object moves through an angle. It is the change in angle of a moving object (measured in radians), divided by time. Angular velocity has a magnitude (a value) and a direction.
Angular velocity = (final angle) - (initial angle) / time = change in position/time
ω = (θf - θi) / t
ω = angular velocity
θf = the final angle
θi = the initial angle
t = time
Δθ = short form for 'the change in angle'
