When displaying a journey, the vertical axis will often represent the distance from a particular place rather than the distance travelled. Such graphs are known as displacement-time graphs.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The area enclosed by the velocity-time graph, the time-axis and the two coordinates at time instants t 1 to t 2 gives the distance moved by the particle in the time-interval from t 1 to t 2.
