One must get the methods of measuring position and time working together if we are to obtain a reliable representation of motion. To that end we have developed a unique system composed of elements ...

The area under the graph can be calculated by: using geometry (if the lines of the graph are straight) counting the squares beneath the line (particularly if the lines of the graph are curved) ...

For a moving object, the velocity can be represented by a velocity-time graph. A horizontal line on a velocity-time graph, shows that the object is at constant velocity, but a sloping line on a ...

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 ...
