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 ...

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.

First, I could try fitting a quadratic equation to the position data to ... Since the average acceleration is defined as: The slope of the velocity-time graph is the average acceleration.
