will not interrupt what you are doing.Covers all aspects of the new GCSE specification, including drawing tangents to estimate gradient of speed-time or displacement-time graphs, and estimating/calculating distance by area calculations.

Q3 on Ex. 2. Should the answer not be 23.66? If you use v=23.66, them the height of the trapezium = v - 3 = 20.66. And if you work back to find the area of the trapezium you will get approx. 155

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.

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!! :)

Ex.2 Q3, Worked solution has incorrectly treated whole shape as a trapezium. Answer should be 59/3
