OK, let's do a simple experiment and use a graph to find a mathematical model. Constant Acceleration We are going to measure distance and time for an accelerating object and use that to find the ...

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.

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient of speed-time and velocity-time graphs represent acceleration.

Then I will find the time interval it takes to go ... Here is that graph. Oh, since these are Jedi the upward acceleration and the downward acceleration don't have to be the same thing.
