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 ...

A velocity-time graph of a journey can give information about acceleration ... eg 50 km due north of the original position. of an object can be calculated from the area under a velocity-time graph ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or ...
