Acceleration is the rate of change of velocity, not speed. Deceleration is the rate of reduction of speed which means, interestingly, that a decelerating object is accelerating.....by definition!! :)

Areas section, exercise 1 1d. Answer given was for 12 seconds rather than the 10 asked for. Also Q3. V is 19.6666... not 28. The question and ppt working and answer needs adjusting. Thanks.
