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} ...

They are afraid to embrace the power of the graph. 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 ...

Now that I'm older, I care more about fuel efficiency and safety than speed ... position vs. time graph for the car based on just the velocity data (and not the acceleration).

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.
