Using and interpreting graphs - OCR Speed-time and velocity-time graphs. In real-life contexts, the intercept, gradient and area beneath graphs can contain information such as fixed charges, ...

The gradient of a distance-time graph represents speed. When displaying a journey, the vertical axis will often represent the distance from a particular place rather than the distance travelled.

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 ...
