Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph. In the first 10 seconds this is the area of the triangle, ½ × 10 s × 40 m/s = 200 m.

At the end of its trip, the pod spends the last 2.6 minutes with an acceleration of -9.8 m/s 2. Question 1: Sketch a graph of velocity vs. time and another graph for position vs. time for this ...
