In symbols, this is ω = Δθ Δt ω = Δ θ Δ t , where an angular rotation Δ θ takes place in a time Δ t. The greater the rotation angle in a given amount of time, the greater the angular velocity. The units for angular velocity are radians per second (rad/s). computer desk with shelves and keyboard tray
