WEBIn equation form, angular acceleration is expressed as follows: α = α = Δω Δt, Δ ω Δ t, where Δω Δ ω is the change in angular velocity and Δt Δ t is the change in time. The units of angular acceleration are (rad/s)/s, (rad/s)/s, or rad/s2. rad/s 2. If ω ω increases, then α α is positive. If ω ω decreases, then α α is negative.
