A formula ... WebThe motion of any moving object can be described by its speed– time graph. Data from the graph can be used to calculate acceleration, the distance travelled and the average speed for the motion.
WebIt is essential that you give two different answers if a question is worth two marks. Sometimes you can gain a second mark by giving the units in a calculation or stating specific data points, eg 'The speed of the object decreased by 8 m/s.' Sample question 1 - Foundation and Higher Question WebAverage speed = total distance moved ÷ time taken = 7 m ÷ 10 s = 0.7 m/s. The speed of the object represented by the purple line can also be calculated. distance moved = (10 m – 0 m) = 10 m
