You know from experience that ... NettetSpeeding up means speed is increasing, and slowing down means speed is decreasing. In other words, speeding up when d/dx [speed] > 0, and slowing down when d/dx [speed] < 0. When speed is not changing, d/dx [speed] = 0, which is outside the bounds of speeding up and slowing down.
