"WebConsider first the angular speed ( ω) is the rate at which the angle of rotation changes. In equation form, the angular speed is. ω = Δ θ Δ t, 6.2. which means that an angular rotation ( Δ θ) occurs in a time, Δ t . If an object rotates through a greater angle of rotation in a given time, it has a greater angular speed. " - Find the mass of a rotating object
