Webto the curve at that time; measuring the gradient of the tangent; As the diagram shows, after drawing the tangent, work out the change in distance (A) and the change in time (B). 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
WebA train travels 50 km in 15 min, and then 30 km in a further 15 min. Calculate its average speed for the whole journey in km/h. First calculate total distance travelled (s): 50 + 30 = 80 km WebLight changes speed as it passes from one medium to another. This is called refraction. The frequency of light does not change as it refracts. The refractive index of a material is a measure of ...
WebIn National 4 Maths use the distance, speed and time equation to calculate distance, speed and time by using corresponding units. 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.
