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.

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.

But if you calculate the acceleration without the graph, you are explicitly stating ... However, if you use other methods to collect position-time data then there could be a non-zero starting ...

Of course with a human jump, I can look at the total time off the ground ... we just have to make the graph. Here is that graph. Oh, since these are Jedi the upward acceleration and the downward ...
