Some aspects of linear motion are more easily seen on velocity-time graphs than on position-time graphs, and some are more visible on position-time graph than on velocity-time graphs. Therefore, it is ...

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 ...

If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve.
