The gradient or the steepness of the graph can be used to work out the acceleration ... 200 m + 400 m + 500 m + 600 m = 1700 m. Average speed = total distance ÷ total time = 1,700 m ÷ 50 ...

is measured in seconds (s) If an object is slowing down, it is decelerating (and its acceleration has a negative value). A car takes 8.0 s to accelerate from rest to 28 m/s. Calculate the average ...
