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 we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding the area. Example. The velocity of a sledge as it slides down a hill is shown in the graph.

The area under a velocity-time graph will give the distance travelled. Lines can be extrapolated in order to estimate a value beyond the measured values, and interpolation can be used to estimate ...
