Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient of a speed-time graph represents acceleration because: gradient = \( \frac {\text{change in y ...

The x 0 is the starting postion (at t = 0) and v 0 is the velocity at time zero. So, for this case, ... But if you calculate the acceleration without the graph, ...
