A horizontal line on a distance-time graph close distance-time graphA graph with distance travelled plotted on the vertical axis against time taken on the horizontal axis. shows that the object is ...

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

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 ...
